Peter Gray and Sons mdl 1911 semaphore lamp.
Another Peter Gray and Sons mdl 1911 semaphore lamp
with applied tag NYNH&HRR.
Interesting to find different methods of assembly in these lamps,
while i have yet to venture into the modern of the PG mdl 1911
lamps types indicated by the large PG on the top cap.
The early production
lamps are found with different retaining rings for lenses and here is another.
Using the same "C" type retainer ring with most back light applications the iron ring has two flattened ends drilled and threaded on one end, which is strange as many draw bands hold fast around the portion holding a lens to keep them secure ,
A "C" ring works the opposite, its spring like tension forces outwardly to hold the lens in place, so why add a drawing feature to a band in this instance ..ive seen a few different PG bands but this is an oddity and one im sure not many of .
The RED RDL is a GENERAL SIGNALS INC MADE IN USA 5 3/8 DIA RDL 7111 in plastic .
Virtually rot and dent free it does seem someone had issues, unfamiliar with "C" bands, bending some very fragile portions which need fixing. The lamp has a thinner finger pull, less beefier bail ears, meager stem keeper but the pot keeper is intact.
This version is without a back light and the side door peep sight is in perfect shape.
