i have 6 cleaning rods for m91/30. 3 of them have Izhevsk stamp about 2" down from nurling. other 3 are not stamped at all. i want correct rod in my 1938 Tula Mosin Nagant as it had 1 of the Izhevsk rods in it when picked up. my 1942 Izhevsk m91/30 had 1 of the Izhevsk rods ,so it is correct. my question finally is "are Tula rods stamped?"
