⭕ This is a 1922 Henderson Deluxe four cylinder engine. The transmission was removed in the twenties or thirties to retrofit the motor for airplane use. As you can see in the pictures the trans was cleanly cut off and a bell housing was installed, the provision for bolting up the plane prop is still mounted on the output. This is not a project or barn find motor. It is built and essentially ready to run. The carb on the motor will need to be rebuilt and most likely the Magneto but as far as I can tell Its all there. It turns over nicely with compression on all four cylinders. There is one broken fin on the top of #3 cylinders , otherwise they are perfect. The motor is an aviation history piece as well as Motorcycle obviously.
