A few years ago I picked up a model 340 in 22 Hornet at a small gun show.Was told the barrel was shot out and it was $150 price tag.Took me 2 weeks to clean out the barrel to show a perfect shiny bore.One item I found peculiar was the rear sight that has a thumb screw adjustment for height.I was able to find an original scope mount and El Paso Weaver to fit it.
Was wonder How does one find the differences between the 340,B,E series and years of production?
