In the Catalog Source Book, in 1942 Wilson had a basemen's mitt called the 'seamless thumb' [Model 563N] as well as 'professional seamless thumb' [models 607m and 607L]. The latter two were the most expensive mitts for 1942.
I just purchased a model 560 1b mitt from 1948. What style web does your Wilson have?
