I checked the bore (good bore and piston) at 52mm so it could be any of these saws. If you know let me know so I can tell potential buyers. Anyway what you see is what you get. I will keep the price low because the shipping will be quite a bunch. How about $45? Carburetor, linkage, air filter, block, exhaust muffler, flywheel, oiler, tank all present and accounted for. Tried to get a pic of the serial but forgot to put it on the macro.
