Oregon chain, absolutely no specs on the pouch.
It is a semi-chisel chain, 3/8" .058" 72DL, has a big "M" stamped on the cutters sides.
Other Oregon, Dolmar, Carlton chains I own have the loops specs or part number written in the pouch.
Oddly enough this one does not.
It is a loop I can utilize, semi-chisel will do fine for bucking dirty skidded firewood logs.
3/8" .058" 72DL is also my most used bar spec, so it turned out to be a good purchase.
Discovering a couple semi-chisel loops in this aged chain batch purchase actually means I have no need to buy any cheapo chains.
Win-win!!!
