Thanks Louis. Ummm, improper was pretty understated,huh? In the collecting of old things over the years I've found the saying "first do no harm" to always be relevant. Or, as a wise old man once told me, if you don't know what you're doing then for God's sake don't do it!
Seriously though, is there some way to increase the contrast without having a professional polisher fix it? I'm just trying to see what's there.
