HB .61 RC Toy Airplane Engine w/ Muffler & Propeller - Helmut Bernhardt, Unused?

Description

This is a very nice HB .61 gas engine made in Germany. I really know nothing about these but this engine looks like it has had very little use. You cannot see any dark spots on the inside of the muffler. The spark plug area is all very shiny. The carburetor is also very shiny and I don't see oil or exhaust stains anywhere. It is marked "
HB .61
" on the aluminum label and "
11.84
" on the motor mount. It has the original propeller and muffler.
The motor measures 4" tall. The muffler is 5.5" long. The wooden propeller is 12" long. From the screw at the end of the propeller to the back of the engine is 4.5". It weighs 1 lb. 4.6 oz.
When you turn the propeller, you can hear compression. I really don't know what to describe or what actually came with this when it was new, so please ask if you have any questions. It will be shipped with the propeller off to save room.
Check out my eBay store for more neat and obscure antiques. I combine shipping, pack securely, and ship promptly.
