I was hoping some of the vast knowledge on this site can help tell me exactly what I have here. I know it is a BSA Martini International 22lr, however I know there are various types (i.e. Mk I, Mk II, etc.) From pictures I have found on the internet it looks like something refered to as a "freelander" model because it has the foregrip and buttstock "thing". This is the heaviest rifle, besides a .50 cal Barrett that I have ever handled (likely 15-20lbs), let alone a .22, this thing has got to be ungodly accurate. I have never shot this gun but would like to know a little more about it and what it may be worth, any information would be appreciated.
