P,
A basic design with very elegant looks, well done that man.
I personally would prefer to see a lot more engines like this, I think it gives a lot of stimulation to would be model engineers and beginners, something that could easily be made without too much trouble and ending up looking rather unique.
I keep going on about Elmers engines, but with a little bit of work and artistic flair, every one can be made to look great with a unique look that only you can put onto it. The more you make, the better you get at it.
Nice !!!
