Barracuda Studios/BarracudaCast resin detail set BR48002 Firefly Mk. I Cannon Barrels

from the manufacturer:

This set consists of two complete sets of resin cast cannon barrels to replace the parts in the Grand Phoenix and AZ Models 1/48 Firefly I kit. One set is for the long barrel cannon fitted Firefly, and the other is for the later short barrel aircraft. The kit parts are overscale and crude. These barrels are refined, with drilled out barrels, and are a drop fit to the kit.
