They are very few, the gunmakers who can design and then construct the whole gun, from muzzle to heel plate. Best guns are traditionally made by teams of specialists, (barrel makers, actioners, stockers, finishers etc). Very few craftsmen master all the specialties of gunmaking. One member of this tiny community is the American gunmaker Dewey Vicknair.
Dewey Vicknair’s latest creation is a side pedal bar-in-the-wood sidelock 28 gauge. It is worth a look. Bear in mind that the double as featured in the posted photo is in the white, awaiting engraving and a stock to the client’s dimensions. The stock you see is a temporary pattern stock. I wish my regular stocks were as well fitted to the metal as this pattern stock!
