These guns were pretty much obsolete and a throwback to WW1 , they were cumbersome and needed vast resources of men to even place them in a position to use them.
I'm not talking about rail guns but large cannons like the K3 of which only 14 were ever produced by Krupps an to quote from the wiki
The K 3 was a gigantic weapon that was transported in six loads. These consisted of the firing platform, the carriage, the cradle, the barrel, the breech and an electric generator.
The Wehrmacht was not content with the gun's performance: "It was felt to be wasteful of time and manpower, the transport arrangements were cumbersome and the performance was not considered to be commensurate with the size of weapon.
The 24cm Kanone M16 which was originally made by Skoda for the Austro-Hungarian forces was also similar in that it wasn't a rail gun , 6 of these were at at the siege of Leningrad and this quote shows that manufacturing new or spare parts isn't that simple as each barrel was constructed of twelve parts, notably the inner tube and various inner and outer jacket pieces and the labour intensive process by which the guns were assembled before use.
Between January and June 1942, part-way through the siege, all six guns had to be returned to Škoda for repair and retubing. This was delayed when barrel Nr. 8 ruptured on 10 December 1942 and a number of roughly-machined barrel ingots in storage since 1918 proved to be substandard. The first two guns to be refitted were shipped to the battalion on 18 July 1943, but the rest were further delayed. The next pair of guns were shipped to the front on 11 January 1945.
It took eight to twenty hours in soft soil or gravel to excavate the large firing pit required to hold the halves of the base box. Six to eight hours were required to actually assemble the gun itself. Each half of the base box was maneuvered into position on rails that ran along each side of the pit and then it was jacked up off the wagon and the wagon was then removed. Each base box half was jacked down onto wheels that ran on the guide rails and then they were bolted together. The complete base box was pulled over the pit, the wheels removed and it was jacked down into the pit. Three rails were placed on top of the base box to guide the carriage wagon into position and the carriage was jacked up while the wagon was removed and it was then jacked down and bolted to the base box. The barrel wagon was guided into place using the same rails and two block and tackles were attached to the barrel clamp. The crew pulled on the ropes and slid the barrel into the cradle. The last steps were to connect the recoil brakes' pistons to the barrel, fill and test the recoil brake and recuperator, and install the roller race. Disassembly took around six hours.
I hope this clears up for Cohen-Slith why it's not that easy to just make new ones
