I got this marlin 30 30 from a guy at work and not sure when it was made. I looked at the post on the top of this page and it it makes me think it is newer than 1990 because of the serial #. This is only my second marlin and I dont know alot about them. I got a 1895 GG 4570 a few months ago and started to get the marlin bug so when a guy at work said he was selling his 3030 I bought it.Hear is the searial# 08025728. On the barrel it says" micro groove barrel " .It doesnt have the marlin eye on the stock like my 45 70. It is a model 30as in 20" barrel. Any help would be great thanks
