IRC S & S Models have a couple of resin / white metal detail sets to change the Cromwell gun tank to a CS as well as a ARV kit . In fact , they sell the plastic kit with the detail sets as well . I'm hoping for a Churchill VII / Crocodile kit . Make sure you save that useless Cullin Hedgerow Cutter from the Italeri Cromwell kit . I've got pictures of Crocodiles with cutters pushing through the hedge rows in France . It seems that the gun tank could push through , ok , but the Croc's trailer would get hung up and sometimes tip , hence adding the cutters to Crocs . And of course , being Canadian , I still would like a Ram OP tank / Sexton SPG kit . Would a Ram generate many sales , I don't know , but I still live in hope someone will make one in plastic
