I came uppon a guy about 2 years ago on ebay who won a contract with whoever really makes poulan/ craftsman/ remington saws. The contract was to destroy recalled saws. He took off all the bars, side nuts, chains, and spark plugs, knocked a hole in the piston, and trashed the saws. Huge shame in my opinion, but I ended up with roughly 8,000 bars, countless bar nuts and spark plugs ( and alot of chains but those are in the personal vault).
All the bars say either poulan, craftsman, or remington on them in paint but at the end where you see the sizing, most of them were laser etched OREGON. and they are identical to the bars in your pictures. So i vote oregon. Also, If anyone wants a s**t ton of bars i need them out of my building.
