Yuri Pasholok found three relatively interesting plans for German stuff. Unfortunately, he published only the markers, but even so, it’s interesting.
So, liked 75mm L/100? Or even 88mm L/100? Think they look outrageous? Check this out – 88mm L/130 AT gun (not a Flak gun, a PaK) proposal from January 1943 – this would have been fun to operate. Too bad Yuri Pasholok didn’t publish the whole plan.
Maus II turret – not a new thing (appeared in Panzer Tracts as well), but it’s interesting nonetheless
And the plans for 17cm StuK L/53 from March 1944 – according to Yuri Pasholok, the gun actually started as a railway gun piece.
