"The lock design was unlike any I had seen before in that it had 4 entries. You had to spin to the first number clockwise, then had to rotate the dial 3 times counter clockwise to the second number, then 2 times clockwise again to the 3rd number, and finally 1 time counter clockwise to the final number as per the manufacturer's instructions. If my grandpa hadn't brought that sheet because I never would have figured that out if he'd just had the combination numbers written down."
