Key made for a 4 Johnson "Cleveland" Farebox??

[BBE]

So is the problem getting key blanks or figuring the actual key cuts? If the lock has been picked to the open position, it looks like one could remove the screw that holds the tang on the back and possably remove the lock core. If the core will come out, one should be able to measure the pins hights and spacings and transfer those dimensions to a key blank.

Not quite. It is first of all a lever tumbler lock and there are eight of them in it. When removing the plug it is highly likely that one or more of those lever tumblers will jump to the ground. I have a number of different styles of Cleveland 4-Way lock and have taken a picture of a few.

From 12 o'clock, a bolt lock that locks both sides of a farebox door, what the inside back of the bolt type looks like, cam type lock, desk or cabinet type lock, a typical plug and one of the lever tumblers and two keys in the middle.

I have never made the keys to this batch ad all the ones that I made keys for are gone. Naturally they also made padlocks. I have seen two styles, a large oval body and a rectangular body. Both bodies are typically bronze.
BBE.
