This is my Ruger No 3 that has been modified. The reason I modified mine was at the time Ruger No 1's in my area were impossible to find and I lucked into this No 3. This rifle has a Ruger No 1 stock set and an added 1/4 rib with a band type front sight. The lever was also modified to make it easier to use with a pistol grip stock. It is very handy and shoots great.
Do you have any close ups of that barrel band? I'm restocking a No.3 right now and that barrel band looks nice. How is it attached?
If I remember right, it is just an Uncle Mike’s magazine tube sling swivel for a Marlin 1895. It pinches together. It is probably not what I would use today with all the nice barrel band swivels available. I can send you a photo if you want one but it is fairly common.
Here is my Ruger single shot, it's a number 3 that Leeper built for me, absolutely everything changed from the decelerator pad to the front sight and everything in between! It's killed more deer than CWD LOL!
Should have some somewhere. yeah, it's a Weaver, I am going to change it however for some higher quality bases to go with the rest of the rifle. leeper did not install that rail BTW! LOL! I'll have to take some, can't find any handy.
