I have what I believe to be an early model 10. There are no date codes on the barrel, just the serial number. (73065) the receiver has the same serial so far... i have no idea what year it is, but believe it may be prior to 1919 based on the serial and lack of date code on the barrel. the breachbolt is fubared... looks like someone took a welder and a file to it at some point in its life. I've seen complete breechbolt assemblies on the auction sites for ~$30. the stock is broken, but plenty of 'em out there. i got this thing a couple years ago for $25. i have no visions of using this for home security... no desire to sell it... something about it calls to me. love the way it looks. if i replace the breechbolt and clean it up- shoot lead shot on light loads... think it could be used as a fun shooter? any idea on the year? any idea if the parts interchange with those of later production model 10s? (fitting of such parts is understandable, just wonder if they're even the same) thanks!
