An Anthony Mount design. A friend of mine bought these castings from the UK and built the engine. I have run it on air, and know it is a good 'runner.' Unfortunately, the builder was a little past his 'prime' at the time he built this model and the metal edges are not finished and polished as they should be. A simple enough thing to "fix", but it will take a little time. You can see the source for this engine at:

and click on "Bensons Vertical Engine."
The castings & drawings are now $345.00 including shipping from the UK.

PRICE: $795.00 plus shipping
