S&G 831 B-M-1

Here is a Sargent and Greenleaf 831 B-M-1 military padlock with a 6 pin Medeco biaxial cylinder. The lock was won of ebay with no key so I had to pick it and custom mill a Medeco biaxial key to fit the lock. When the operating key is turned the locking cam rotates out of the grooves on the shackle and the lock opens. The control key is an operating key with the top and bottom shoulders removed.
