Rare saws at my local saw shop
Went in to order some parts for my riding mower and looked up and saw a McCulloch BP-1 balance piston saw, that thing is huge! It was also in near new looking shape, the large size and weight apparently made them not too handy to use. There was also a Stihl rotary saw, the ignition system apparently went south on that one. Apparently people went into the shop and gave these to them, pretty cool 
Just thought I'd share what I saw with some fellow small engine junkies

RE: Rare saws at my local saw shop
My favorite vintage setup is a O&R gas engine powered drill. It had about 1 hp and had a 1/2 inch drill chuck so you could drill holes out where there was no electricity.
About that Mac BP-1 chainsaw, I think someone used to convert some of them to a twin cylinder RC model airplane engine. They would convert the second cylinder to fire also.
It was on the market for a very short time, the factory feared that if the governor failed for some reason the engines could over-rev, disintegrate, and injure the operator. They used a cast magnesium crankcase and there were rumors the engine could ignite the crankcase in some cases, but I doubt that was the reason it was discontinued.
