I have one that my dad bought for around $10 at Woolworths five and dime circa 1954. It's sportorized and shoots 2 3/4- 3 1/2 inches at 100 yards.....but it's about 15" high for it's fixed battle sights for I'm guessing to 300 meters.

My dad said it wouldn't hit the broadside of a barn if you were in it. When I shot (with big cardboad!) he was suprised it grouped so well. I'm sure that he was annoyed as youth to have to deal with fixed battle sights set high and that's where he got the inaccurate notion from.
