Supposedly a rubbed oil finish was an option at one time from what I have read on RFC.
Yours is indeed a beautiful rifle! The peep set-up would likely work quite well for my eyes now... it was how my T-bolt came set up as well (2nd ".22") and I remember it shooting quite well. Who knows, I may come full circle before it is all over!
These 513S's are hard to find in almost any configuration. I have never just "picked one up" sitting in a LGS. One of these days I need to shoot some "quality" .22 target ammo like BSA and others shoot to see what it will really do!
Sitting in a grove of KS cottonwoods in the fall picking off a few Fox bushy tails is still on my bucket list.
