Comparing manufactured guns to trade made guns is much like comparing boxlocks to sidelocks. All four catagories can produce a "best work" gun. Manufactured is for high production numbers and trade made is for versatility. Parker sold a high percent of a large number of relatively pedestrian guns. Purdey sold a high percent of a relatively small number of "best work" guns.

Is Purdey's the Parker of the UK?
