Title: My 202 D1 from Associated Telephone Co LTD
Post by: dsk on July 23, 2016, 01:20:37 PM
Removed some dust, and fitted new cords, now I have to make a subset!
When I turned the dial center this popped up, how old/new may that be?

An my holiday trip I found this in an antique shop.
Never heard about Associated Telephone Co LTD before.
Picture before and diagram.
Seems original to me.

The base is marked D1 USA, and stamped inside with red ink: I 37 and in the metal B-7.
The dial is marked 29  and CB with red ink, and the metal is stamped A.E.Co type 24
The hooksw. has 2 N.O. (on hook) contacts.
The handset  is E1

How could the dial center have been in about 1930?
What have I actually got my finger into?

Working on a compact subset without ringer.

It looks like your D1 went through a refurbishing house. Because the cord and dial aren't original, I would guess that it was set up for manual operation the original handset cord was frayed or broken.

Now that you replaced the cord, all you need is a nice #4 or #5 dial to complete the originality! Nice find!!

According to the diagram glued in the bottom plate, it is the right dial, this is obviously note a pure W.E. phone.

Here is the subset (without ringer)
The unit is put in to an old laptop power-supply, and made for plugging in the 4 prong plug from the table stand.
The circuit is made of different parts I had based on the idea of the triad-type circuit.
It works great!

Wiring diagram later.

Here are the diagram with desk stand and subset put in to the upper right corner.
The original drawing is a Kellogg.  As you see it is based on the same idea, and it works great.
