Cool Coin Bank
New(er) post office box door/lock. It is 35 years old, and was a post office door from when they stopped making combination locks, but had not redesigned the door without the combination lock letters.
Reverse Yale keyway, and I had a few five pin blanks.
Well, needed to figure out how many pins, so I stuck a flashlight in front, shining light through the window, and looked into the keyway.
OK, try the blank.
Made in 1980
And no pins in the core.
So, without much difficulty, now the bank is once again functional. It will go back to its owner soon.
