Engraving is similar near as I can tell. Arcaded fences the same. Seven pin and detachable locks the same. Aguirre y Aranzabal engraved on lockplates on my 1980s gun; not on yours. Engraving and physical design can change. I'm saying I don't have a good grasp on features which would distinguish 1 from 2 from 117. Think ChiefSG is correct that it's not a model 53. I've never seen one except in fotos but the engraving on a 53 does appear to have some "definition". Engraving on a No.2 looks like kudzu; it's everywhere but not going anywhere, not really taking your eye to a destination
