The reason you can't find much information on it is that it just wasn't imported into this country in large numbers (nor was it even produced in large numbers). Italy and Spain have LOTS of small mom and pop firearms manufacturers that make shotguns (mainly over/unders). The vast majority of these firearms never leave their country of origination. Some are not well made. Others are fine, well crafted firearms. Unfortunately, its hard for us here in America to know which brands are good and which are not.
When I was in Italy in the Navy, I stopped into a few gunshops and got to handle the locally made stuff. Some of the wood they use there is beautiful.
