Of all those I think I like the PMR #1 the best , its not what I would suggest as a beginners build , but the elegance is memorizing , that large thin flywheel is difficult to turn down on a lathe. I have owned all of these engines at some point.

I watched the PMR #1 run on YouTube...it seems to have quite a long stroke for its size, think that enhances the look running. I may give it a go IF I have fun machining the PMR #3
   This engine would look nice in a real Dark green or Dark blue IMO
