This work was actually started just prior to WWII in England with the introduction of the fold crimp clousure. It was completely finished just after the war & fully reported on by Burrard at the time. Both Thomas & Bell could have saved a lot of time & trouble by simply reading "& Understanding" his work. Both took statements of his concerning "True 2 3/4" shells loaded to a higher pressure level than the standard 2½" shell out of context & attempted to make him appear wrong. Even today shells should not be fired in a gun, regardless of chamber length, loaded to a higher pressure than the gun was intended for.
