Bucheimer was one of the major holster companies when Safariland & Bianchi were ideas in the mind of their founders. If they've become collectable, I need to start digging through closets.

I believe they produced the issue holsters for such departments as the Pennsylvania State Police, NY State Police, Philadelphia Police and others back in the day. I'm not sure whose holster had a steel finger inside the trigger guard as a retention device [NJ State Police?] (putting your finger inside the trigger guard to release the pistol causes spasms in liability lawyers now).

They also produced "sportsmans holsters" or field holsters.
