Post Office Key

I don’t know a lot about this key. I picked it up at the same radio club auction that I found the Lionel J-36 at. I’ve searched for the markings online and didn’t come up with much other than it was from the Post Office. Haven’t even got an estimate of the date, but there are similarities with the RAF Type-D so I’d guess probably pre-WW2 by a little bit.
