Did you get this phone completely finished Ken?
With code number 1902 do you think it is a "Type 19"? That coding/model number relationship held true for other AE phones in this time frame I believe.
I have never seen or heard of one of these AE phones before. Someone must have one in their collection!

That would make sense, indeed. They were number 1902 and later 1903. There perhaps was a 1900 and 1901 in the beginning too, and they never seem to have acquired an L-code.
Type 19 is not used by any other instrument, as far as I know. The Type 18, I think, was a wall instrument with the L-900 receiver on top. That would leave only the #20 open until we get to #21 which is well known, of course. Is it known why the No. 21 was numbered that way early on ?
