GEM, thank you very much for all the information. I find that you said that Jon Speed's appendix shows that 199341 is the highest number listed interesting and needs a change as mine is 199366 only 25 higher. With all the information that you gave me I now know what to look for. I bought the gun as a project it had a clogged barrel. I thought that there must have been a bullet in the barrel which I hoped to be able to remove. Well, I was partially correct there was not one but 4. I first measured with my cleaning rod for the muzzle, it went in about 5 in. then from the breach. I found that there was a distance of about 6 in. difference so there has to be another bullet. I taped the rod and to my surprise, it moved so I continued tapping. First, one then two then three, and finely four. They were pellet size which I have never seen before. Anyhow after cleaning the barrel, it is mint. I shot the gun at 100yds. with a great grouping. This gun is definitely a keeper. Thanks again GEM for all the information.
