It is a bit funny that the seller has them posted as being 1938 22.5 wheels when the tubeless tire was first commercially used on the 1954 Packard and not by Chevrolet on 1 ½ ton and 2 ton trucks in 22.5s till 1956. I have a set of these wheels on a 56 1.5 ton GMC and the bolt pattern is the same as that 38 but they are not original on that truck. This guy has a buy now price of $1500 wow if they go for that my GMC is going to be sitting on brake drums LOL.
