I'll make contact with the museum and see if they can take measurments. Appreciate the link to their web site.

Your photo shows how amazing the support logistics had to be. I've read accounts from six years earlier during the fighting in the Netherlands where the 4.2" mortar platoon would fire off 3000 rounds during an offensive. Hard to imagine what it would take to transport in that many rounds.
