Disaster averted! Tried the magnet on a string, crawling on all fours with a flashlight, but could not find it. Luckily my Dad had some parts, and it was identical to the lost one. Thanks for all of the advice; was able to install the new one and try it a couple of time to get it to work properly. I had to adjust the arm that goes in and out on the threads of the thumb lever and she is ready to go. I had to take the screw out of the clip because the old stock was hung up on it. My dad bought the rifle from an Eaton's catalogue way back when, for the tidy sum of $16. He fell down while moose hunting and split the rear stock it half, but a friend if his bolted and glued it back together. He used it for adout 20 years like that, but I guess the stock was shrinking and it became loose. He is 69 now , hopefully he will use it for a few more years yet.
