It may be quite valuable, or it may not, I've not ever heard of that brand. Lots of companies in the last century plus used house names on factory shotgun, like Sears used JC Higgins, and the gun may be something like that, or an obscure British maker.
More,tho,were made in Belgian and other European factories and given names similiar to famous British makers, I've seen guns marked, "W E Richards" to imitate Westley Richards,etc.
BTW, thousands of cheap but workable shotguns were made for every example of a "Best Gun",so the odds are against this being worth the price of a good car, but it does happen.
Whatever you do, have a gunsmith check out the condition of the piece before you fire it. Lots of old shotguns are chambered for shells shorter than those of the present time and firing a modern shell could be hazardous.
Also, bbl steel has come a long way, some of the old stuff was made by welding strips of metal together and the bbl gets weaker at those interfaces over the decades.
Hope this helps...
