Yeah, it's an Investarms, the same company that makes Lyman and Cabelas. Depending on the details, lots of folks will like it because it's a 58 caliber, and in all likelihood a 15/16" barrel. As far as I know it's been quite a while since Investarms made a 58 caliber, and those from many other companies have 1" barrels. If in fact yours has a 15/16" barrel it will be lighter and most, which translates into a tradeoff between lighter weight for comfortable carry, but the potential for more recoil.
Photos and some description of it's condition would help folks provide a lot more detail. And in fact, I'm speculating till I see the photos.
