Carried on with the last few pieces of the light today.
Finished the machine polishing, then carried on hand polishing it all, followed by reassembling it all.
Found a patent number on the support arm, also ended up polishing off the chrome on it, which came off really easily, leaving a solid brass arm.
Finished light against the cab for detail.
Proposed position for the light on the truck.
So quite a lot of time spent getting this light from before to now and I must say, the wear on it actually appeals to me.
