George....check where the finger stop is. If under the finger stop, there are two holes it is a #2 dial that was made into a 4H by WE. There would also be patent dates around the edge of the dial. Before you go parting the phone, check the dates on the base ringer and the elements. Does it have a grill under the grip to pick up the phone? H1 of H1-3 engraved over the mouse hole. Riveted instead of screw on feet?....Doug
I'm uploading a picture to Facebook now, one that I think shows the two holes you're talking about. I'll put it here, too.
There are dates on the back dial around the edge. Some of the dates are obscured by the remains of the gasket.
But I can make out:
WESTERN ELECTRIC MADE IN USA
PAT[obscured]SA
AUG 13 12 AUG 24 15 DE[obscured]Y718 SEPT 13 21
The metal case is marked H1. There is a date inside but it only says NOV 5 and the year is smudged. It's a long ear, though, not a short ear with cooling fins (or whatever they are).
Base is marked 11/40. Ringer is marked 11/40. But transmitter says 5/41.
I don't think this is anything special in particular. :-)
Is it good or bad that it might be a #2 made into a #4H?
