28cm Kanone 5 mit Lastenträger Tiger II (speculatively illustrated)

Further speculation from the Walter Spielberger Tiger Book
A most interesting project was begun in 1943 at the instigation of the army. It was decided that, owing to the increasing intensity of Allied air attacks, a railway gun should be developed that was capable of cross-country detours around points at which the track had been destroyed. The gun itself was also intended to carry an integral turntable platform so that it could be lowered to the track and the bogies run clear, leaving the weapon ready to fire from the platform with 360° traverse. This idea resembled the American 14 in M1920 rail gun, but the idea was then carried further by a suggestion that it should then be possible to partly dismantle the K 5 and transport it across country on special transporters based on the chassis and running gear of the Pz Kpfw VI (Tiger Tank). In this, one transporter was to carry the breech mechanism, two were to carry the barrel between them, two were to take the gun-carriage and one was to move the platform. The mounting was also to be designed to take either the barrel of the 28cm K 5 or a new 38cm howitzer with a planned range of 25000m (27340 yard) with an 800kg(1764lb) shell. The whole project received a great deal of thought and would no doubt have been successfully completed in due course, but it was still in the planning stage when the war ended.
[1]The profile drawing of two Tiger IIs carrying a K5 doesn’t match the text description though, which says the whole load was broken into 4 loads transported by up to 7 Tiger IIs.
