Stay far away from any of the ten shot versions, the safety versions suck I think any of the ones made in as late as 1980 would be OK. I have one that comes from the 1950 that is sure a nice rifle. The one I shoot the most often is a 1975 rifle and I really like it. I have one from 1998, that is pretty but is a real mistake.

Thus saith thr lord; Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeh from the lord. Jeremiah 17:5 KJV
