Picked up this little Model 61 yesterday, neat old rifle and really fun to shoot. Had it out to the range this morning and the Weaver 29S, although a bit foggy, was perfectly usable.
I think I got a pretty good deal on it for $510 out the door. The butt plate is missing, and was replaced with a clear plastic spacer and a 1" Pachmayr recoil pad. I removed the pad and spacer and the LOP is 13 1/4". I put the spacer back on for my trip to the range, I'll likely replace it with a Galazan 1/2" red recoil pad. The gun is also drilled and tapped for the Weaver side mount, and has had a set of sling swivels installed, including drilling and tapping the magazine tube hanger. The modifications don't negatively impact the shooting experience, and made the gun affordable to me so I can live with them.

Very well. Didn't put it on paper (and likely won't, I have Anschutz's for that; this gun is for fun) but it did put the hurt on the 25 and 50 yard silhouettes at my range.

There is a company that makes a lot of different replacement grips and butt plates for the older guns. I don't know the name of the company but I'm sure that someone on this site has that info and you might be able to purchase a properly marked plate for your rifle that would dress it up nicely.
