I'd reach out to Vintage Doubles in Wenatchee.

Rather than a brand, Eibar is a gun making region in Spain that has produced SXS shotguns exported to the US under various brand names. With the cheek piece, I suspect Richland Arms. This area of Spain is in the Basque region and I suspect Zabela is the actual maker. Google "Eibar double barrel shotguns" and it comes up with photos (perhaps of your gun) and some interesting history of the region.
