These blanks are for older (but not the oldest) Bargman locksets. If your Bargman lock was made from 1969 to 1976, this may be the blank for you. Please carefully inspect the photograph before ordering. Notice that there are no grooves on one side of the key. And there are two wide grooves on the other side. These blanks can be used to make backup keys on any key cutting machine. Photo shows both sides of blank. Price is for one key blank.
