I'll admit to being a little confused when I requested this assignment. I was expecting something else. Still, these are very welcome components as I have two 1/72nd scale Spitfire Mk.V’s in my “to-build” pile.
The Spitfire was among the earliest production fighter aircraft to adopt a 20mm cannon as armament; with the “B” arrangement for the cannon being introduced in the Mk.I and Mk.II models that fought the Battle of Britain. While the success of the armament was spotty at that time, it became the standard on the Mk.Vb [the same guns also found their way into the initial production Sea Fury]. The earliest Mk.Vc Spitfires also used this pattern of gun barrels before going to the “beefier” barrels as standard (parts that Master also offers separately). So these parts are not only compatible with the Spitfire Vb, as advertised.
