Odd badged Dayton chainsaw that is hard to find info on as it isn't a true "chainsaw".  It was built by Poulan of Wrights design.  It basically carries a lot of the big body Wright reciprocating saw design in a compact form. These were badged under several different names: (Poulan 100, Allis Chalmers 85, Wright 100 and Dayton 2Z464). I wouldn't be surprised if another one was to pop up badged under a different name either.  As for how they cut, slow and smooth.  I can see it being used for butchering, timber framers and log cabin builders as it would make a cleaner cut for exposed timbers and live edge logs with the way the blade cuts and it being of a mid CC range (59cc's).
