4 x 12mm Aluminium Tube. The Hs129 B-3 was the B-2 variant fitted with a semi-automatic loading 77mm Pak 40 anti-tank gun adapted into a lighter-weight, fully automatic aircraft-mountable version, with a completely different and more aerodynamic muzzle brake to produce the Bordkanone BK 7,5 model.A huge hydraulic system was used to dampen the recoil of the gun, and an outloader system with 12 rounds in the magazine was fitted in the large empty space behind the cockpit. The gun and its recoil mechanism occupied a gun pod under the fuselage and a hole in the rear end of the pod allowed spent cartridges to be ejected.
The resulting system was able to knock out any tank in the world, but the added weight further hindered the already poor performance of the airplane. So few operational B-3's were made that after much debate and deliberation we have decided to include only the standard B-2 decal sheet and leave it up to the modeler to source their own specific decals A SUBSTANTIAL RESIN KIT TOTALLY HAND-CAST IN DERBYSHIRE, UK BY GREY MATTER FIGURES AS THIS KIT IS LABOUR INTENSIVE WE ONLY DO OCCASIONAL SMALL PRODUCTION RUNS.
