Well done. Now you can sew the "greaser" badge to your sleeve.
My primary ggun is unbranded, and gifted to me by an uncle in about 1970. It has performed faultlessly since then, so must be over 50 years old.
Another relative gifted me a Wanner around 1980, but despite the Wanner fanbase, I still prefer my unbranded ggun.
I use a Wanner gun from about the same period - much better than the more modern one I have.
