I bought a Finnish M27 this week that has the Tula "Hammer" marking on the underside of the tang but there is no date or other marking there. On the top of the tang there is a small oval with an unidentifiable marking inside. Any idea when this receiver was made? Sorry, but I can't make out the marking even with a magnifying glass and light. The M27 is a Tikka, dated 1934 on the barrel. Where would be a place to buy missing crossbolts for the "popsickle" stick nosecap and the barrel band, also needs a cleaning rod. Thanks for any information. This M27 was sold as a parts gun for $50 as the barrel looked like a sewer pipe. However, after much brushing with Hoppes, and rapid firing 40 rounds, it looks pretty good. With this purchase I now have a 31, a 33, two 34's, and a 39.
