Your 1935-A originaly had a painted finish, which looked like hell, but protected the gun well. A close aproximation can be obtained using Brownell's Baking Lacquer in matte black. It's fairly easy to use in the aersol can; follow directions. In it's present condition, $75 to $100 as an example, restored, maybe $125 to 150. Do you have the original holster? That would add something, depending on it's condition.
