I just received this phone today. It mostly looks better in person than in the listing pics, except that the listing does not show the damage to the shell below the cradle. The cradle and the piece which sits below it are both broken in half, and the glue which had been holding the pieces together apparently let go during shipment. I bought this phone mainly because of the Fuld handset. I actually already have a phone similar to this (forum link (http://www.classicrotaryphones.com/forum/index.php?topic=8345)). The other one is from the 1950s while this one is apparently war-time. The transmitter and receiver elements are dated 1939 and 1940. I didn't find any dates inside the phone other than a 1939 date printed on the wiring diagram.
The handset is in excellent condition. As far as I am aware, these handsets are rather rare and possibly somewhat valuable.

Handset pictures.
That is the standard early handset of the company, perhaps until the mid 1930s, I think.
T&N and Fuld are the same company, but nevertheless a nice piece to get at that price!
Ow, I like this one. It is a Maingau 38. (shallow casing, the lower rectangular part of the shell in later versions is higher, earting button to the side).
The handset is somewhat rare, but I think it has the same rarity as the phone itself. At least for this version.
The handset has an older version, with a more pronounced spine. That is more rare and more valuable.
Pity the number window is missing. The plunger is a standard part found on many German phones, so replacable.
I have its brother, by the way.
I didn't know if these phones had actually shipped with that handset.
Larry
Is this phone also an egg carrier?
Those are the ringer gongs.
Larry
AHHH, yes. Thanks Larry, I should have seen that!
I have been working on this phone the past few days. Since replacement cradles are not easy to find around here, I am trying to repair this one with super glue. The handset is is excellent shape. I am curious about a couple of emblems embossed inside the handset parts. Can someone here identify them? I am also attaching a better picture of the diagram inside the shell.
Thank You
Larry
The left logo seems to read HRS, but I can't place it right now, although I have seen it I think.
The right mark is the logo for the German institute for material testing, MPA, and it identifies the manufacturer and the material of the piece that bears the mark, by the codes in the logo.
If I read your logo correctly it says "22" and a sideways "S" ?
For example here is the MPA mark for a Siemens phone:
The "MPA" emblem has a "32" on the top and a sideways "S" below. The other one probably is "HRS", but I have no idea what that is.
Thank You
Larry
Ok, I found the picture where I have seen the HRS logo before.
It is on a German finger wheel which has the same logo.
The logo is by H. Römmler in Spremberg, Germany.
I have a 1938 list of MPA codes, which lists this company as having code no. 32.
PS: alright so that matches your code.
The "S" stands for phenol resin with wood filler, which is the typical Bakelite. I think that is the same as "31" code that Siemens&Halske (34) used, as in my symbol.
This radio museum has this listing for Römmler: http://www.radiomuseum.org/dsp_hersteller_detail.cfm?company_id=12661

I found that link just before you posted the message. Now I know who manufactured my handset.
Thank You

The same radio museum site also has a list of the MPA codes, seems to be the same that I have:

The phone has been reassembled. The transmitter had far too much gain and made alot of static noise, so I connected a 330Ω resistor in parallel with it, and it sounds much better, though still not very good.
Here are a few 'after' pictures.
Larry
Looks nice, I would be proud to own it.
Is this phone supposed to have a spring somewhere under the cradle? When I lift the handset, the hook switch doesn't always close completely, so I have to pull the cradle with my fingers.
Larry
It looks really good now, Larry. Very well done.
Mine has no spring with the plunger. The spring is in the hookswitch. Probably it is running a bit dry or it is sticky. Clean the holes and plunger, oil it very very lightly, I'd say.
I decided to take this phone off the shelf and dust it off a bit. I noticed that there was a bakelite ring inside the transmitter cup which fit around the transmitter capsule. With that ring removed, there was enough space for an AE type 41 transmitter to fit, so I bent the contacts inside the handset a bit and installed an AE transmitter, and now the phone is usable with crackling noises.
Larry
Larry finally got the phone working thanks to your diagram, very pleased as all the bits are original including transmitter and receiver although a bit noisy and that's to be expected. The cradle spring is on the phone under the contacts and not on the cover,this may help as I know this was mentioned. Thanks again another phone for the collection.
