The sizes are about right.
First from the early 1930s
Second from the late 1930s and ran through WWII to 1948
Third is modern
The first Universal joint is from the early 1930s, the style changed in the late 1930s and ran through WWII. The last is a modern piece, in 1948 the style changes and ran through the late 1970s.
The difference between the F-80 and the F-80 is size. The F-80 is much bigger. There are very few early universal joints. It appears they were weaker and after years of use, they break. The F-80 is a much beefier universal joint.
