Or a guy like Wiig surely knows someone who casts.
For such a genius it's really no problem to build a prototype in the own hut.

The saw is family.

Look at case, its very close to identical in shape and material.
Close, but no cigar..

It is pretty clear to me the case is almost identical to comet. In end of case to the rear, there is a tap/mount that isn't on Bo's saw. All screw holes are cut and re positioned... I think that is about the only differance on the case from what I can tell.

I decided I think this is likely a saw made from a Comet.
Very much thought went in to this and the carb/injector is a mystery in itself.

Would it be possible that maybe this saw was built as a school project say at a college that had the tooling to do so?

I know when I was going to diesel school that the machinist students were building 1/16 scale horizontal hit miss engine's. I personally got to see a few of them they were all different in ways. The one I remember best ran from a burning WIC. Looking at this saw it appears to me someone built this using a como comet as a base design.

It is pretty unlikely given age and casting etc.
The schools here at the time that could do this were at a bit higher level and focus on stuff that make faster money easier than saw production.
