I was fortunate to have available a few sets of original bushing retainers (washers) and Dave purchased one of those sets. As far as my reproduction retainers, they are new stampings (not just refinished) and are very close in appearance to NOS. Brown zinc dichromate is the original finish, but there is no actual documented "recipe" available, and some of the elements of the original may not be available anyway, due to EPA regulations, so the although my current offering is quite close, I am still tweaking the formula as development time permits.
