The five-inchers were already finished bar one barrel that will be replaced out of my Aber set at the last moment to avoid another loss. For the 18 20mm Oerlikons I got a second set of Master Models guns, that will take some time and will come later on. The single Bofors or the Chicago Piano's are still lacking, all Bofors were needed in the LST project. What I will show here are the double 40mm Master Models guns, coming from a sixpack. These really are the
nec plus ultra of ship upgrades, with unprecedented detail as well as ease of construction.

You can observe the PE, the barrels, gun cradles, accompanying director on its own pedestal, the double gun breech printed with holes for the barrels and the shell case ejectors.

In this manual you get multiple views per step, with all detail of the parts present so you don't have to guess on what side the PE needs to be bent.

First you place the seats and the brass ejectors.

Elevating wheels and gun cradle rails are then added.

The directors with 3 PE parts and showing bolts etched on the flange.

No need to drill the hole for the barrel and even the visor is simple and elegant to add. The elevation mechanism on the underside is also in PE.

All is fitting as designed.

I used the Bayfield maquette for the position of the director, even though a 20mm was shown on that location. I don't see where else these cradles can be fit.

The barges have been painted and are ready for soem railing, but I doubt about the colours still. i already showed this foto in the LST topic:
