British version of US Browning .30 chambered for the British .303
round, and was used as a basic fighter aircraft gun.
Version with flash hider used mostly as a defensive (flexible) weapon
on bombers (Lancaster, Wellington and other), but also as a offensive
(fixed) weapon (e.g. on Mosquito).
Set includes four turned brass barrels with slotted cooling jacket. It
is very simple to use in your model, and makes it extremely realistic.
Simply cut off the original plastic barrel and drill a hole in the
remaining plastic parts and insert the metal barrel using Cyanoacrylate
