German S-100 Class Schnellboot

The SBoot 20mm Flak Cannon 

There are a number of armaments aboard the S100 boats, in the tub on the foredeck sat a single 20mm Flakvierling cannon, dimensions below are for the 1/20th scale.

This is my drawing of the forward 20mm Flakvierling Cannon.

Amidships there was a twin 20mm Flakvierling cannon, again dimensions below are for 1/20th scale.

This is my drawing of the twin 2cm /C38 Flakvierling cannon.
