Can anybody provide insight into what size(s) jersey Gil McDougal wore during his career? Reason I am asking is that there is currently a size 40 jersey of his from 1956 on ebay......

.....however, in the Grey Flannel Holiday Auction ending last December, there was a size 44 jersey attributed to him from 1955.

While different jersey sizes during a career don't surprise me, I am a bit surprised to see such a differential one year apart. Just wondering if anybody can provide some insight.
