Here you can see some trimlines, and they are mostly western electric but there is one from stromberg carlson and then a few from AT&T.
A tribute to Gramma and Gingha and this is what the green western electric with the white handset looked like that was in their kitchen.
Western electric 500 from 1950
The above is the Gramma and Ginga telephone as seen in Grammas kitchen.
Just made an appropriate instruction card for this payphone and it came out pretty good.
