The Dickson round action guns have a very innovative design that attaches the lock parts and springs to the trigger plate, and uses arched springs as opposed to the 'V' springs traditionally favored by sidelock builders. The arched springs are less prone to breaking, but still offer fine, crisp trigger pulls. SInce all the action mechanisms are mounted to a single, unifying component, they are far less likely to get out of adjustment. Another innovation is the placement of the ejector hammers in the action bar, instead of the forend. This also aids reliability, makes the action bar short and quite strong, and centralizes the weight of the gun well between the hands.
The Dickson gun shown above was made in Edinburgh and delivered to the new owner the day before grouse shooting season, in the year 1893. Originally built with 30" Damascus barrels, the gun was rebarreled by the makers in 1959 and fitted with a fine set of 27" compressed steel chopper lump barrels, bored 1/4 and 1/2 choke. It weighs 6 lbs., 3 ounces and is a lively gun to shoot. The lovely French walnut is original to the gun, and wood like this is very hard to find now.
