I saw this listed on e-bay and thought that it was rather nifty: Vtg Antique Circa Auto Truck TURNPIKE TOLL GUN Hot Rat Rod 40s 50s 60s 70s NOS

"Here is a NOS still in the box Turnpike Toll Gun. It just don't get any better than this. The box has some wear and one corner is torn. It has other nicks in the box as well. The gun looks new and dusty but it appears to not ever been used."

This thing would probably get you shot by a policeman if you pulled it out in order to use it.
