4,5" gun case

4.5in steel
I don't know for sure but I think it highly unlikely that British technology in metal drawing would include making steel cases that large. We still dont use steel and did not then have the shortage of copper that pushed the German industry toward utilising steel for cases. 2pr

i,ve run into them for old U.S. 105mm
4.5 steel
I took it we were discussing the 4.5in naval gun case which is nominally 27.5 ins long and 6.5ins dia at the base with quite a hefty neck. Bear in mind the British car industry could not press a car roof panel in one piece without it crinkleing at that time, then drawing big cases is pushing it for the technology of the time. However I am only going on memory of metallurgy lectures from years ago and we all know the pitfalls. If someone can come up with a steel one please do. 2pr
