In 1938 the multi-stripe piping was replaced in favor of a thick red stripe. This thicker piping is known as a Soutache braid. The uniforms were otherwise unchanged.
The Pepper Martin jersey above is clearly a 1938 based on the piping pattern and buttoned uniform, however for some reason the 1939 patch has been added to it. This jersey might have also been worn in 1939.
While this Frisch photo is handwritten with 1934, we know based on this uniform look that the photo is from 1938.
