For get electroplating done of assemblies with multiple parts, like door and lid latches. can plating be done without disassembly? Other ideas?

Yes. I have done all latches on 914's without problems

yes
lube all pivots when you get it back from the plater.

Thanks!

Absolutely can plate them as one piece.
I think they should be clear zinc....not yellow zinc.
But obviously you can do anything you choose.....I did.
