King Arms Thompson modified to resemble British Spec. Thompsons used in the early years of the Second World War.
This model has the charging handle slot filled on the right hand side and a new one in the correct place milled in with a new (non-moving due to space) cocking handle fitted.
The rear sight is based on the Lyman sight used on the early guns, it is a non-adjustable model but does have both the aperture and open sight options.
Furniture is wood, with the battery compartment accessed through the buttplate.
Some minor modifications have been made to the barrel mounting to remove wobble native to the design.
