Anyone know if this is a permanent part of the wheel?
That may be the Floyd Clymer whistle. It told you when you have the right pressure.
Willys Knight wheel.
WOW! that's amazing that you can tell that is Willy Knight just by looking at his hand. You know, he may be airing up a friends tire so therefore it's not his wheel.
Or, it could be the big W with the faint word "Knight" below it on the hubcap...
My experience has been that the hand/s and air line are not a permanent part of the wheel. Tests have shown that the wheel can even be used to separate the fingers from the hands !
Everybody is probably sick of my old newspaper advertisements but I know just a little bit about Willys to know that they were popular in this area and in the 1940s they paired up with Ford to produce the first Jeeps for military use.
The advertisement is from 1929... I bet that the car in the picture is earlier but it seems like Willys separated from Willys-Knight in the 1930s.
Don't breathe blue air...
