I guess overnight the handguard decided to shed. Wasn't anything I did, a couple pieces were just laying there when I picked up the handguard this morning to inspect.
I guess problems should be anticipated whenever you buy something that's 80+ years old as "new".
Fortunately this is a minor piece, and doesn't really affect anything (you can barely see it), but I can't let it go. A repair will be in order.
