3.7" Ram

[ramtank2]

I have seen photos of a Ram chassis cut down and mounting a 3.7" AA gun in a rather awkward open mount.
While surfing the net I noticed a statement that General Mc Naughton while reviewing a parade in which the 3.7" AA Ram was present made the statement this vehicle is not so much the basis mobile heavy AA capability, as it was to provide a heavy anti tank platform in case the Germans are developing heavy tanks.

Some info from web scores says prolonged firing of 3.7" at low angles overstressed recoil system, could a muzzle brake had solved this?

Instead of the open turret mount could the Ram chassis have been fitted with a casemate mounting a 3.7" for anti tank work.
A la the German tank destroyers and Soviet SU types.
