HI well i think it is a gorosabel they did market a windsor deluxe they sold for 644 pounds in 1981 [have the catalouge] it was one of there best guns they marketed it shound have hand detachable locks,gorosable uk didnt make guns they were a marketing group and had guns made for them from my info they had zabala,arrieta,and even ? gullia from memeroy they were a bit like Army and Navy back in there day .This doesnt look the same as the pics ive got of a windsor deluxe .Just to add a bit of a twist there was a spainish maker called P GOROSABLE and they made guns to all different price points and called them all sorts of things i think there are a lot of better guns around for that kind of money cheers
