Up for your consideration is a vintage West Ridge (Warren, Pennysylvania) Operator System 13 for Hat? Shirt? Badge.  This was my great uncle's when he drove bus.  He eventually drove for Greyhound, not sure if this is a Greyhound line or not? We believe it to be from 1930's to 1940's time period, as he was born in 1897.  It is 2.5 inches tall and 1.34 inches wide.  Truly a unique piece.  Please see all gallery photos.  We are a smoke free, pet friendly home.  Have a great day!
