I completed restoration of a Postal Telegraph SI-15 (Hammond 341) Illuminated Wall Clock 15-inch glass illuminated metal case wall clock from around 1940. Clock was stripped of paint, de-rusted and repainted. The three chrome pieces were re-chromed by a professional chroming shop (the left chrome piece was previously damaged - the top line of the fin is missing). All electronics and wiring save the motor were replaced (five 7-watt candelabra type LEDs and E12 sockets, new ball socket switch, RF-controlled wireless light switch kit to power on and off the LEDs, original parts saved for sake of completion). This one is definitely a keeper!
Pictured next to the Postal Telegraph clock is the General Electric 1L1215 clock that I restored last year (apologies they are not yet synchronized!).
The final two photos show the clock during restoration - with the repainting of the clock body completed and the 3 chrome pieces de-rusted and stripped of paint but not yet re-chromed.
STUNNING!
Those lighted Postal Telegraph clocks tens to sell for really high prices, up to $800. I have a non-lighted bichronous one that I bought a few years ago from an ebay seller for $150. The lighted Telechrons can also go for a few hundred. I have a very nice 1L715 that I bought and restored this past summer. Unfortunately, the rotor seems to be failing now, and replacing the rotor involves dismantling most of the clock.
