Simshaz, that looks very like an Erbi. It was Spanish made for the English market. You should find the name Erbi stamped on the bottom of one of the the chambers, next to the lugs. Also on the bottom of the barrels, just forward of the chambers, you should find some star shapes stamped that will tell you the chokes - not 100% certain, but I think the Spanish convention was 1 star for full choke, 2 for 3/4 choke, 3 for 1/2 choke and so on. If that is wrong, no doubt an expert will put me right shortly. Nice little gun - just the thing for a knockabout. PW
