Does anybody know what kind of material was used to hold this base over the barrel? It looks like a tin. Thank you.
Indeed Bill, we live in the 21st century. A good epoxy glue, used and applied with the utmost respect and following the instructions to the letter is (IMHO) better as whatever soldering. I know, I know ... professional gunsmiths overhere consider it as "the easiest solution". They are right of course, but ... it works! And it works well. For myself and a couple of friends I used epoxy on sights and mounts for a couple of decades now. So far nothing "fell off" and it will not! Ask your plumber, he doesn't work with the same ingredients of 50 years ago.Not sure what you are up to with the mount or what you want to put it on, but you could heat and wipe off the solder remaining, and then use epoxy to hold it to the rifle. Sounds funky I know, but works, and is far easier to remove if you ever need to without hurting the rifle finish underneath.
