It was a Mossberg Model 146B, tubular magazine, .22 bolt action rifle.
Purchased when I was age 14 from a Montgomery Ward store, "on sale", for $25.00. NIB. This was in 1955.
Now like an idiot, I sold it in 1968...for...$25.00...and thought I got a good deal!
Damn, I was young and stupid.
I wish I still had it. It was a wonderful, well made, accurate rifle. Besides that, it was stocked in a beautiful piece of well finished, dark walnut.
Here's a picture of one I found. Sorry for the photo, but it was the best I could come up with.
