I fully rebuild them. I have them oven baked, chemically stripped, bright gold zinc plated, then I powder coat them semigloss or high gloss black for a beautiful finish. Then they get re assembled with lots of grease and new bronze bushings. Cost is $150 + $25 core charge for 914s. I have the parts to build over 20 sets in stock and ready to be built.
If interested give me a call at any time. 951 536 7478 -Bruce.
