hi all.

another curious question. i own a ludwig supersensitive in very nice condition. (keystone badge, sn. 303844) loads of pitting on the lugs, but almost nothing on the shell....

inside the shell i can still see the stamp that reads (...). July 1966. also there is some kind of signature in the shell. could that be original? it looks like someone wrote a "b" or a "9" on the inside the shell. someone seen that before? or could that be done by someone afterwards? something in me hopes it's brass but that's probably a wrong feeling..... anybody knows anything about this?

thanks, michael
