There were two Sarasqueta makers, not related, Victor Sarasqueta and Felix Sarasqueta. Victor Sarasqueta was at one time, one of the best Spanish makers, quality wise, and earlier guns/rifles (yes, one of very few Spanish makers to make double rifles too) from this maker were of better quality than later ones. I have had several of their guns, and found them to be quite good guns, for the money. Some of their double rifles tended to be a bit crude, and I have seen a few with ribs slightly off center, etc. Champlins firearms recommended against their double rifles, to several friends, because the rifles tended to not hold up well over time, due to some soft steel internally. Felix Sarasqueta is not in the same class as Victor S., and Felix S quality is less, from my experience. Modern Spanish guns/rifles tend to be of better quality than earlier ones, in general, as I believe that all Spanish makers have decided to make better quality guns/rifles than they once did. I assume that the Dumolin (not sure that is spelled correctly) is a Belgian gun, and if so, if it looks good, I would buy it, for some very nice guns came from the Belgians.
