Details

This defence Ro422 has been superimposed on an old French fort of 1674 vintage that was built would you believe to keep out the English. They have used the four corners with Tobruk's, placed a Vf221 5cm Pak inside and then cut out the corner of the forts wall and placed a very rare bunker in its place. This R139 is a February 1939 designed bunker more for the west wall but as the Kriegsmarine were building bunkers earlier than the Heers (army) they tended to use the older bunker designs. This is the only one left out of possibly four that may have been built. Also it is 'in mirror'. Meaning the design has been flipped horizontally. The plan shows the layout inside with two gun rooms, one for a 4.7cm Skoda Pak and a heavy machine gun behind 78P9 plate.
