Antique German 4 Barrel COIN CHANGER Brass Ticket Dater Leather Strap Railroad For Sale

Offered is a very rare four barrel coin CHANGER by Prof. Alfred Krauth of Eberbach/Baden, Germany. It is fully outfitted with a leather pouch and shoulder strap, and a brass ticket dater/validation stamp that rests in a brass housing wrapped in leather. The housing would have been holding ink for the stamp. The whole unit is in excellent, vintage, light used condition. I was told this was purchased at an antique shop in Germany in the mid '70s and it was possibly used on the railways, trams or buses in the mid/early 1900s. It is in museum quality condition, a bit dusty inside, otherwise excellent for it's age.
It measures roughly 8" across, 6" tall and 2" thick.Thanks for looking!
