Congrats -- it looks like it's in great shape, and impressive that you found it in the wild!!! I've got one and I think you'll like the way it shaves....takes a standard GEM blade. If you're interested in Lather Catchers, I'd like to invite you to check out The Association of Lather Catchers: TALC.
I actually just picked up one very similar just with the metal handle instead of the wood. I'm excited to get it in my hands and try it out. Love how my Gem Junior Bar shaves so hoping this one is just as good.
