This appears to have been done a long time ago and is often seen on older DI's. Recently purchased this Spring: WWII Collection of DI's ( over 250 ). Nearly every one is a Pin Back ( PB ) or Screw Back ( SB ). All were collected during WWII and up to the Korean War. I will list as I have time or how well they sell.
