Postal Dept Revolvers ?

[MikeP]

The local post office had pistols in holsters bolted to sorting cases until the late 60s. Somebody shot the time clock and they confiscated them.
The Post Office, when it was a department, was well armed. I think that ended when it became a semi private organization about 1970.
They even had Thompson SMGs on some mail cars and the "HYPOs"old rolling sorting offices in buses.
My grand father worked as a clerk on a "Doodlebug" A single unit with engine, baggage and mail section and some passenger seats.
His was on the CB&Q Line.
He had an issued Colt Snubby that he had to turn in when he retired.
I don't recall the markings, I was just a kid.
