Assistance please. I purchased yesterday 91-30 with marking "star" with an 'arrow' inside. 1939 My researching at 7.62x54R net says it's a Tula. only some small ?square? looking thing in front of the star. What if anything else should I hope to find. Them 'bands' man oh man; how in the dickens do you remove them without tearing your fingers nails up. Research @77.62R and they said nothing.
