Correction to my request for information of April 9, 2007.

The shell casing is 8 cm by 35 cm! my error.

Headstamp?

Without knowing exactly what the “8cm” is measuring (rim diameter? Calibre?) a likely candidate would seem to be the 75x350R case originally developed for the French “75” field gun which was acquired by the USA in WW1, then used for the WW2 75mm tank gun as fitted to the Sherman etc.
