Saying hello from the Pacific Northwest. I have 2 marlins, both 22 self loaders, one model 60 and a model 50. Both guns were given to me at different times by different people, just call me lucky I guess. The 60 is a great shooter and very accurate. The 50 is missing a few bits and pieces but is generally in nice condition. My goal is to get the 50 operational again as my research shows that it is rather unique and rare. Not a lot of information on them out there so looking forward to meet some other 50 owners on the forum to compare notes with and ask questions of.
