Very rare armoured part 'found'

Seen on Atlantikwall Superforum today. Le Duke visited the roof of the Keroman III U-Boot bunker in Lorient and photographed a 1P7 Eingangsüberdeckung.

This very rare armoured part was thought be built only in a Regelbau 514 in Turosl in Poland. The 20cm thick ceiling of the cover was as protective as 2m of concrete so it could be used when a low profile entrance was necessary, in this case on the roof of the U-Boot bunker of Lorient, Keroman III.
