Hi F Bill, when I saw the lack of radiator mounts, I realized my 3A was not a 49 but maybe a later 50. �Who knows at this point since the data tags are missing. �I'm thinking the T-90 may possibly be a 46 as the wagon input shafts are much larger. �The PO could have just used an available case and replaced the insides. I'll know for sure when I remove the tub and can place an eye on the casting numbers. �
FYI, I picked up a 43 GPW last weekend. �The body is toast and the frame has been butchered. �However, the drive train, axles, and leaf springs are in decent shape. �
