Can anyone identify a 'vasco' shotgun?

[Alex_Zues]

I found a shotgun which the seller referred to as a Commercial Vasco 12g sxs. No more information beyond that. Can anyone explain to me what it is? I can't figure out anything about the model, company that made them, etc. Type it into google and all you get are musicians and 500 year old explorers. If they've got some history, I'd like to know what it is

Any proofmarks or writing on the barrels or receiver?

If it's basco with a "B" then it may be a Spanish made double.
