Not uncommon for wheels to be measured in the wrong spot. From the pictures, as Manager pointed out, they appear to be the Kelsey 4.5" which can be found at about a 20:1 ratio to the common 4" in these parts. For some reason, I always ask the price when seen at the swapmeet and find the 4" in average condition to regularly sell at $75 after the negotiation, and the 4.5" may go for the same to twice that amount depending on the seller's knowledge. In places where supplies wildly vary, prices are all over the place also. Demand for the 40 spoke Kelseys has reduced in recent years as the trend toward 17" and 18" Ford wheels responds to the availability of good tires. The 18" is my recent choice for open wheel use. Twenty years ago 18"s showed little demand. Having Fun: Fred A
