"VirtualMec does not offer images of the lamp holder, lamps, chains, belts or the commutator.
To include them in my drawing I improvised some cluster of parts which functions as a mock-up to indicate the location of their presence there."
I think he has made a good job of the drawing and improvisations. At least there is no danger of smashing the lamps!
