Welcome to the greatest thing you are going to see for a long time. This restoration is on a Barco BR-5 Rammer made by the Barco Mfg. Co.. This marvel of insane engineering is technically a 2-stroke motor with no rotation and two pistons. You read that right... The tool can actually keep running without human input, slowly stomping down the street, crushing everything in its path, and the only way to stop it is to grab the handle while in motion and hold it up so the top piston can no longer trip the magneto. That is the only off switch. Other than the horror, it's insanely fun to use and is great at children's birthday parties and cideries.
