Well, if you post the model number, and all the funny little lines on the gun (called WORDS) we may be able to tell you who made it for Montgomery Wards.
Galvanized is a term for coated in Zinc- usually done to limit rusting- and NOT done to guns. If the barrel is a dark black/blue, that is bluing. The frame may be a light silvery/tan with mottled rainbow colors- that is color case hardening.
Post some pictures for us. Unless the bluing is long gone, it is amazing what you can do with light oil, a COPPER pot scrubber, followed by a wipedown with clean soft cloth.
