You're in, Bob. You're in charge of the yearly banquet.
BTW I assume you've cleaned the inside of the receiver... I recently cleaned mine for the first time (second-hand gun, and I haven't shot it in about 10 years because the last time I did the extractor decided to vacate the bolt). I had cleaned the barrel and action as well as I could without field stripping but I didn't have a manual and didn't want to break anything.
Well, long story short, I have never seen more gunk, grit, sludge, and general funk as I found in the trigger group and action of my 31. Holy smokes.
I tried Hoppe's, I tried a toothbrush, I tried q-tips, I tried scraping it out with a screwdriver, I tried brake cleaner
... I worked on it for about 2 hours in all until it was clean enough that I wasn't embarrassed to be associated with it.
I still couldn't get all of the crud out of the receiver, partially because of the horrible design. Lots of little shelves, nooks and crannies in there... not to mention the back right of the receiver is completely open to the wooden stock!
I was dumbfounded by that design decision.
Pity, because I personally find this rifle to be one of the more graceful designs in .22 semis. I love the triangular-cross-sectioned palm swell in the forend, and the thin (and fragile, I'm sure) wooden slats that extend to the rear of the receiver. It handles and balances beautifully for me, and I love the overall lines of the rifle.
Now if I could only find the proper extractor... I'm not sure if mine is a single or double claw. I suspect the latter but I don't want to guess wrong and order the wrong part (which I've done three times for other guns).
Also, am I right in my observation that the only serial numbers are INSIDE the receiver, on the top? That's the only place I've found any numbers...
