This is a REAL railroad key.
The International Great Northern wording is largely rubbed, but still obvious. I cannot make out the words/numbers on the back. One looks like a 3 and one looks like a K. There are a couple of notches on the barrel. As they are straight lines, I would assume they were on purpose maybe to tell which key was which without looking.
