The Type 51 dial was the first with the spring assembly that is no longer removable in one piece.

That is what I am not convinced of.

I don't think I have ever seen a cast dial with removable spring assembly - but that doesn't mean there isn't one.

It appears reasonable that phones during WW2 would not have a rubber shoe around the bottom edge.

Yes, that is why I suggested earlier that the material base was released during WW2. I think originally rubber was used, then material introduced during WW2 and then a return to rubber (or faux rubber).

If that is the case, the phone in question is early, but not the earliest.

It looks like it has Chicago not Chicago 7 on the tag so that means it is NOT any newer than 1943.

So no patents any more recent than 1943 on there Karl? Or do you wind up actually seeing the date that each patent was actually granted which could go into 1944 and even 1945?

The latest patent year on this label is 1939.   I listed the patent in an earlier post in this topic.  My coding for patent file names is patent country and number first, then issue year, then application year, applicant(s), company, and finally exact title. Comments are last in ().
I am adding the list again to the intact image.


The handset patents, also those for the transmitter and receiver capsules, were approved in 1940, which are not on the label. Therefore the label was likely produced earlier than 1940.

But we really don't know why they included certain patents and not others, or how soon they updated labels after new patents were granted. It is a bit of guess work and only a guide.

I don't have any 40's with the black felt covered base myself though I have one in my records with some info given to me by a member "recrum" but he hasn't been active here on the forum since 2013. I sent him a PM and an email to see if we can get some more info on his felt covered 40.

Meanwhile, a trip into the spare parts box yielded this black felt covered base for a 40 without the rest of the 40. It doesn't have the usual paper patent label on the bottom but it does have its schematic diagram intact inside. The drawing is D-53688 Issue 4 and the telephone was a N4038 B0. The ringer that is still attached to the base is a low impedance SL ringer which looks correct for a 40xx set with a "0" ringer code.

One other piece of evidence is that it still has the special brass "nut" on the forward base mounting screw which was used to attach the front of the base plate on 40's that had the old steel dial mounting ring as opposed to the newer bakelite cases that had bakelite tabs to attach the dial to.

I wish I had this phone intact as I don't have any complete felt based AE 40's!

Here is one that sold last week:

http://www.ebay.com/itm/232185894943

Unfortunately the interior of the set is not shown, but by the patent label it may be directly inferred that it was made between 1939 and 1943, and in context of other known patent labels, that it was made between 1939 and 1940.

Hey Fabius:

Can you confirm that the schematic diagram has N4020 on it, can't see the letter for certain.

Also can you see what 2 letter code is on the bottom row if printing on the small condenser and if you can see what is printed on the large condenser.

The picture that shows the induction coil makes it look different than normal. Is it marked D-282996-A?

And finally, any chance if a closer look at the dial and markings on the back.

Thanks,
Terry

Here are some quick shots - sorry they are not as sharp as they might be. Not enough light, not enough hands and no camera mount.

Since you are using a Canon EOS 70D camera with some meta data, I'd think one of the 5 images you tried to load had a random string within the image that caused all 5 images to no load. Resizing the image at least one, or just the offending image (you could try loading those 5 one at a time to see which one has the bad string, resize it and try loading it again).

The meta data attached to the last image you posted is attached to this reply in pdf format.

Having created a lot of combined images for the auction contest gallery and Find of the Month winning phones, I ended up with 2 or 3 that did not load and offered what I found to work best  when dealing with the security "Error" issue, which come from 1 of 2 issue or in the worst case, both in one image.

After resizing the problem images, they loaded without further issue.
