Fairly certain your shotgun was made by Boito, and imported by the now defunct Firearms Import Export Co of Florida.
Boito produced- well, some pretty clunky shotguns. Here in the US they were mainly sold thru discount stores, like K-Mart, W.T. Grant Dept stores, etc. Value of yours is in the $50-$75 range.
My favorite gun is a side by side 12 g Boito. You see, my lady bought that for me for our first wedding anniversary. Still have it. Not the prettiest gun in the safe, not the most expensive, not the best made. Stock has been repaired when it was splitting behind the tang. Still my favorite.
What we have here is... failure- to communicate.
