WCLX apparently built cars to its own designs. I don't think that there are any accurate WCLX models besides the Sunshine kits, but it may be possible to kitbash one. afaik the Rapido reefers are not accurate for WCLX out of the box as they represent a GA design.

Accurate kits or models of WCLX, CRLX, NADX, Swift, and Armour meat reefers are sorely needed in HO imo. Almost every 1940s and 1950s consist with reefers that I've checked contained at least a few examples of the above cars.
