Journal lids were often not manufactured by the foundry that cast the trucks, but were a specialty onto themselves. Different railroads could, and did, order different style lids. In later years it was not uncommon to see a mix of styles on the same car, even on the same truck, especially on cars in work service.
The journal BOXES, however, are part of the side frame casting, and should be the same. Differences likely arise from different placement of the parting line for the model part, and different theories of how much draft angle is needed in the mold.
