Blood,

I believe you have a BSA Martini Cadet No 12. (Although it is possible, but rather unlikely,you may have the larger action Peabody-Martini Cadet.)

Over 100,000 of these types of guns were made by BSA alone. They were also made by W.W Greener and Webley and Scott.

The reason you are having difficulty finding info is the fact that most of these converted years ago into a variety of aftermarket calibers. One of the common conversions was the .22 Hornet. More than likely your gun was converted in the 50 or 60's when these actions could be found by the box full for 4-5$ a piece.

LOL.....I am too tired to fill you in on all of the details....So....do this for me. Go to a newstand and pick up this months (Sept/Oct) copy of Rifle Shooter magazine. Flip to page 14 and you will find a five page article about the history of this gun, including info on conversions and its use as a varmint gun....(You owe me one....)
