The B/O badges were made with a peel and stick backing with an acrylic adhesive. Here's one that was never used. It was "liberated" from its assembly bin during a tour of the Chicago factory back in the mid 1970's (I didn't take it but one of my classmates did and I traded him my factory reject souvenir drumstick for the badge during the bus trip home).CaptainCrunch said:For a small one, like a Ludwig Keystone or Gretsch RB, they didn't bother and I don't either. But Ludwig used rubber cement or something like it on the B/O badges, and Gretsch SSB and later can spin. I think the picture mounting tape sounds like a good compromise.
