[Fot] Lucas RMS 576 Roof Mount Spot Light - Parts Schematic needed and LENS for the 576 lamp

[Justin Wagner]

Does anyone have a parts schematic for the Lucas roof mount spot light 
of the 60's, etc.?

Something seems amiss in one that I have acquired and I'm thinking maybe 
a past tinkerer might have lost an internal part, etc...    I'm racking 
my brain here with the unit disassembled before me.  There's a threaded 
shaft that doesn't thread into anything.   I know Lucas has odd ways of 
going about things, but threading something for no reason doesn't make 
sense.   A parts diagram would be very helpful.

Secondly, the lens is broken..   Does anyone have an original lens 
laying about for the Lucas 576?
