The M49 was a single shot based on a copy of a Martini action made by Ithaca. There was also a repeater version of it made. They were configured to look like a lever action rifle due to the popularity of cowboy movies in the mill back then. They were made from 1949 until about 1970 IIRC. They were also private labeled for Sears (Ted Williams Model 40.530430). Fun little guns. They have weak extractors, so be nice to it.
