Hi Ludvig, your'e right!ludvig wrote: ↑01 Aug 2015 18:58Hello Sturm78 .
Thanks for a interesting photo of 27 July 2015 .
It looks as an 21 cm SKL/45 in Verschwindlafette to me . Notice that the gun
has an horisontal breech block , the 15 cm KL / 40 in Küstenlafette C / 07
had vertical breech block . If you compare the gun barrel with photos /
postcard from Essen in 1913 it matches .
Krupp produced at least 3x different types of Verschwindlafette :
24 x guns 15 cm KL/40 in Küstenlafette for 5 x CD batteries
at Danzig , Swindemünde and Borkum
1 x gun 21 cm SKL/45 prototype at Essen Later Meppen
4 x guns 28 cm Kst. K . L/45 in Verschwindlafette for the Belgian coastal
fort Doel outside Antwerpen . These guns were confiscated by the Germans
in 1914 and later used in Battery Deich ,Wilhelmshaven - But in WW 2 some
of these gun barreles reappeared as 28 cm schwere Bruno rail guns . Two
28 cm schwere Bruno railway guns survived in Norway in 1950 s .
Discussed photo it is really 28 cm L/45 gun. Caption with place name Schillig also confirms your location = Deichbatterie, entry to Wilhelmshaven bay. Alredy picture is again offered on Ebay.
An interesting article about that location: http://mariengymnasium-jever.de/mgjever ... start1.htm
Pitty, but former battery area is destroyed by developer now.
