I'm more of the shooter/collector type. My 1'st nice gun, English Army&Navy sidelock, top lever ejector. 2'nd a Edward Whistler, London made back action top lever hammer gun. 3'rd Gaspar Araziga very nice Spanish side lock ejector...Hooked! Tend to like them all, hammer guns both back and bar actions, side locks and box locks. What I find most interesting is bolting systems. I do like side levers and under levers. Great for clays and hunting. If shooting a clay pigeon ring the top lever ejectors rule.
