The first pilot turret was demonstrated in mid-December. In January 1944 a pilot turret was successfully tested on a Grizzly chassis. Due to the challenges of welding a turret of such a complex shape from Rolled homogeneous armour plate, Dominion Foundries of Hamilton was contracted to produce a fully enclosed cast turret (One of the largest armour castings ever made in Canada).
