I bought a padlock over the weekend from a garage sale.
It looks pretty old, about 5" tall, weighs about 2-3 lbs. It has a brass plate on the front that reads;
ALCATRAZ San Francisco 68
There is no other writing on the lock or keys. Works good.
Anyway, Its not for sale, but I'd like to find out more about it. I'm hoping to hook up with a few collectors out there, can anyone suggest a good starting point?
