While researching the 1941 Wilson "Streamline Kurv-Form" patent I found the patent illustrations included a variation for an outward facing seam.
This patent variation is beautifully crafted in the early 1950's "Andy Pafko" model 2080
The out-seam was nothing new in glove manufacturing. I ran across dozens of patents in just a short time online. From the beginning of the patent era, Hand and work gloves used this construction. I chose this one example because it is so well illustrated and such a great design! This 1909 work glove below is wonderfully detailed and features out-seams of the fingers and sturdy reinforcements of the palm seams.
This leads to my favorite glove of the 1910-20 era, the Goldsmith model TB "Illustrated Lion Pocket" glove. This model was Goldsmith's top of the line model circa 1917-1922

- the "Lion" stamp is at the right of the pocket

- note the stitched leather webbing between the fingers
These gloves are shown at
