A rebadged Poulan 5200.  I believe the largest saw Dayton had rebadged from them. Above is a link to Poulan 5200 for a bit more info. The Poulan 5200 is not an easy saw to find and being badged Dayton is a bit more rare. I have seen a handful of Poulan 3400 or 3700 rebadged for Dayton and even less of the 4Z252 Dayton's. Again, these are just Poulan 5200's painted Orange with Dayton decals.
