Thank you streetlight98 for the welcome and reply. My form 400 is the late style pressed aluminum. It has a GE 510 which has crack through it
I will purchase the M400 A2/R2 as last resort.
In Santa Monica, Ca. they are doing a mass replacement and hopefully will get a early M400 series remote from the workers. There is a large qty. of them on the west side. They all have 510 glass in them. Got my eyes on some lovely early OV-20's and OV-35's soon to go.
I will post some pics soon.
Have collected over the years:
OV-20 stamped
OV-20 cast
Form 400 circa 1957
Form 109
Westinghouse 60's gumball
3kw "Hollywood special" (iconic massive triple OV-35 whiteway) some of these ended up in a specialty shop in Hollywood after removal in 2005. First thing to catch my eye when I moved to So. Cal. In 1978. Awesome to see when cruising the boulevard at night back then. For me anyway.
