Hello. my name's Nate. I'm new to this forum, well, I should say a new member. I've been coming here for a while to get info, and since I now own two marlins (model 60 and 336A) I figured its about time I join. Anyway my question is regarding the date of my newly acquired used model 60. the serial number is 06215xxx. From what I have learned so far the date code is supposedly 2000 minus the first two digits. which would make it a 1994. I've also read contradicting info saying that 06 might mean 2006, and on the other hand 2006 models used serials starting with 94. So, I'm pretty confused. The guy I bought it from said it was only a few years old. It doesn't appear to be as old as a 1994. My rifle has the 22'' long barrel, 14 round mag tube, and the last shot bolt hold open feature. However I read that the newer models have the short 19'' barrel. Am I wrong in assuming that 2006 would be considered "newer model" and should have the 19'' barrel? meaning that mine probably is a 1994? So between the confusing date coding and not being able to find exactly when these came with shorter barrels I'm at a loss dating this thing. Any help is much appreciated. thank you for your time.
