I have been looking for one of these for a while, but the cases are always cracked. Can't crack this .....its metal!! It cleaned up beautifully. It was advertised as bakelite but by examining the cradle I though it was metal. Paint is just amazing. This is very cool. I love the Redbars, but this is just the one I have been waiting for, the push to talk or dial. You do not see many of them...Doug

Doug, what is the function of the Push to Talk lever? How is it used?
It's more commonly found on the wall-mounted version of this model. Nice. It's for party line service, so the caller can check first to ascertain the line is not in use, before dialing.
Doug, that is a very nice looking, stylish phone. Great buy!
thanks guys...I've been looking for a long time.
As Karl said, it was for a Party Line so I am going to leave the original frequency ringer. This does not ring, but I want it to be accurate. ...thanks to all....Doug
Doug;
Great find, you didn't buy it you stole it.
I really don't understand the concept of push to dial/talk ?
What happens when you lift the receiver off the hook, is the phone dead ?
D/P
Before pushing the button, one could monitor the line and hear either an idle line, talking, ringback or dial pulses. One would hear dial tone only if someone else had gone off hook and pushed the talk button, but had not begun dialing.
You can duplicate the idle line condition on any WE/NE 302, AE 40, Kellogg 1000, or SC 1243 by temporarily removing the transmitter. In fact, that's a good test of the secondary circuit. With the transmitter disconnected, the receiver is in series with a capacitor and the central office doesn't see the phone as off-hook. Installer/repairman butt sets have a monitor/talk key which in monitor position is like this phone before pushing the talk button. That's probably how Captain Beefheart was able to answer the phone before it started ringing.
Nice phone, Doug! Paint is in really terrific shape!
What is the ratio of Bakelite to metal Redbars out there? Which version is considered more rare?
AFAIK, metal housings on Kellogg 1000 Masterphones are nowhere mentioned in the catalogs and brochures. The 1000s were supposedly introduced in 1947, and even the brochures of that year mention that 200-ton presses are used to mold the resin.
Roger Conklin, who worked for Kellogg for a long time and wrote an article on the Redbars for the TCI Singing Wires, didn't mention their existence either.
It's hard to imagine that metal housings were introduced later, as the entire industry moved away from metal housings to plastics because of the cost advantages. WECo stopped producing them in 1942. Kellogg had produced telephones from Bakelite already in the 1930s, the 700-series, 900-series, all were made from phenol resins, and all are most often chipped or broken when found today.
It is rather rare to find a metal 1000-series, I would say, I have only one of four or five 1000-series sets.
Perhaps the metal cases were special-order items for use in rough environments or the military, but I have found no references to that effect. I also don't recall seeing any special markings on the metal versions.
The standard version with dial is a D-1000, while the Doug's sample here is a D-1001 indicating the press-to-talk switch. Following this, the model would have the ringer specification added, for example D-1001-HA2 for a 50 Hz harmonic ringer (http://www.classicrotaryphones.com/forum/index.php?topic=11938.msg126866#msg126866).
Here is a metal redbar that had a magneto. It was retrofitted at the factory with an almost new base. Paint was horrible. I have it on eBay this week. ..Doug

I love those push to talk red bars. My "phone guy" who operates an antique and collectible telephone retail shop and repair service actually has quite a few of these for sale in his shop. Party line service was probably more common around my area though which is probably why he has so many.
Does anybody have a diagram for a push to talk 500 type set? I have a north with 500 type wiring that I'm not sure how to get to work.

Fig. 6 shows wiring for cradle-switch latch for N-542 etc.

Thanks, The diagram looks like a switch on the cradle. However, the north I have has a momentary switch on the handset.

Then you have to examine what kind of G2 (type) handset it is. It could also simply be a switch to control external equipment, or it could shunt the transmitter. How many conductors does the cord have?
So the handset has a 4 conductor cord, however the transmitter and reciever share one lead, (R).
One lead shorts to the BK when the button is pushed. Let me inspect it further.

Here is a picture of the base and the ptt switch, the white and the black wires next to the coil go to the push to talk. As much as I want this to ring, I cannot make myself swap out the original frequency ringer. I want this as authentic as possible. I have added a NOS Kellogg line cord as this came without the line cord...Doug
I wouldn't swap a frequency ringer either.
Among collectors, I would call it the act of a charlatan.
The sound of a 54Hz ringer is an interesting event in itself adding to the experience of a historic phone.
It is easier to find a proper ringing source than to find some of the rare phones people own.
Some test sets, such as the Sage 930A, provide frequency ringing signals.
It is also not hard to modify a Panasonic PBX to provide frequency ringing. See for example: http://www.classicrotaryphones.com/forum/index.php?topic=11948.msg127016#msg127016
This Masterphone has a no. 15 Kellogg dial, if I can make it out correctly. I think the no. 15 dial was a copy of the no. 51 or 52 AE dial. This phone would therefore be dated after 1951 (#51).
Since this phone appears in great pristine condition, I would say the dial is the original dial and this would date the entire phone with the metal housing into the 1950s.
Could it be that the metal housings were the last Red Bar phones to be produced, before Kellogg switched to the K500 series in or about 1954? Perhaps Bakelite as a material was now considered too outdated in the American market to make a favorable impression?
Roger did mention metal housings in a July 27, 2014 post on the TCI listserv (emphasis added):
To convert the 1070 to common battery, the local battery induction coil 114-A has to be unplugged and removed and replaced with the plug-in 113-A common battery induction coil. Then you can install a dial and it is ready to function as a dial phone.
I have one so converted. I removed the magneto and plugged the crank hole by gluing on a circular disc, and added the dial.
The 1070 housing is metal rather than the normal Bakelite usually found with the common battery version of this telephone. (Some common battery sets were also made with normal-size housings for phone companies that insisted on metal housings.)
Roger
I just looked at the auction pictures of this phone and those show the bottom where the phone is marked D 1001 HC2 15D
This means it has a 60 Hz frequency ringer (HC2). 60 Hz ringers are very easy to ring, as all you need is an isolation transformer for use with utility power. The transformer would safely isolate the telephone from ground. An AC relay could be used to turn it on by the 20 Hz ringing on a phone line, or other ring-activated switches. There are for example lamp switches available that turn any regular lamp on when the phone rings for people with hearing problems.
These sure don't come up very often. I can't tell if this one is bakelite or metal. Either way it looks nice.

I think it is Bakelite. But surely not easy to tell. I think the metal shell is thinner in the place that is shown from underneath, and would almost with certainty have some wear on the edges there, showing gray metal.
Dial is broken, at least in very funky condition.
Dave....I think it is Bakelite, but I have been surprised before. Dial looks like it needs a little lubrication. They are cool phones.....good luck....Doug
it almost looks like metal around the red bar, but I agree I think it's bakelite. the price is a little rich for me - plus the $25 shipping! someday I will have one, but I'll wait for a lower price.
I always email a seller and ask if they will ship the phone medium priority and tell them how to pack it. Most will do it. This seller is new and probably has no idea about a medium priority box. I agree, I would not pay $25 shipping on principle alone....Doug
