jckeffer, Hey. As I said in my post (Re. Wife wants to shoot long range ), I gave my 62A to my wife. It is the one she really likes to shoot, and I take her to the range several times a year to break clays and stuff with .22's. I grew up with that rifle, and being the youngest I ended up with it. Then I taught all my kids to shoot with it. (and a whole bunch of others). I have a sweet shooting Model 61 hammerless as well as several bolt .22's. I asked her which one she wanted and her choice was obvious.
I would not do any restoration to one of these as it does take away value. Mine was rebarreled just before my dad got it sometime in the middle 60's. Also mine has a very small and smooth (no grooves) forearm. I have never seen another like it, they all have the long ribbed one like yours.
My care for the 62A is I have been wiping it down with 3 in 1 oil for 40 years stock included.
