To me, "natural" or "plain" makes me think of "metal". Something like this: I'd think that it would be perfectly acceptable to do that or paint them the same black color as the frame.
I'm not really THAT anal, just would like to know what they were on the 53. Since I have new ones, and they would be really easy to paint. Doesn't appear to be much info about them for a complete "correct" restoration.
" Natural " This means the cast iron body wasn't painted at all . I well remember the lever shocks being a satin black color .
Corrosion Resistant They're cast iron and so don't need to be corrosion resisitant , only the innards will be damaged by corrosion .
Nate, you're describing single action shocks, '49 and prior. Ol' chebby is talking about shocks for the '53 he's rebuilding, so they should be tubular type shocks.
Natural finish I've used both of these and love them...real nice metal looking finish, like a dark metallic gray. http://www.quantaproducts.com/prodinfo.asp?number=07-01 http://www.napaonline.com/Search/Detail.aspx?R=MSR7250_0006419575 Bob
