Thank you Blindstitch. I had previously looked at Ebay and couldn't find what I needed, but, after your post I looked again and found what I wanted for half the price plus free shipping plus it's already on the way here.
Anyway, the rifle wouldn't extract the shell after it was fired. I let it sit on the shelf for 2 or 3 years and last weekend decided, after watching a couple of videos on the topic decided to work on it myself. After a thorough cleaning and bending the wire the way the video shows. I test fired it and it works like a charm. The screw had been gone for some time.
