I manage a crew of locksmiths, need some Christmas gift ideas. Doesn't have to be tools, they got what they need to do their job. Just looking for some cool locksmith related items.
It’s a number 77. Production range from 1945-1993, 1996. Or at least that’s what a little bit of Internet research says. Take it with a grain.
It’s cool that you have the keys for it
you might be able to narrow down the date range a little bit more if you were able to find out when Master Lock started putting key codes on their locks/keys..
The design on the head of the key may tell you more as well.. I’d try to find an old guy at your local locksmith shop..
