21” rim hub flange

What is the width of the rim hub flange on an early 21 inch spoke wheel? According to ‘ The complete model a Ford registration manual’ page 363 by Les Pearson the early 1928 is narrower than later 28&29 but does not give me a measurement.

Re: 21” rim hub flange

My "B" style wheels (the later Model A wheels which became standard after the brake system changes/hubs were complete) measure 1-1/2 from the point where they meet the hub to the "turn" of the wheel pressing.

IIRC (I'm not finding this in my literature) the same dimension on the AR wheels is 1-1/8".

To confuse the issue further, there are nearly the same size (will take the same tires) and identically made wheels aimed at the 1926-27 Model T. These wheels are different yet. I can't tell you specifics on these.

Elsewhere is reported the Model T spoke 21" wheels are a 5" bolt circle. Model A is 5-1/2"
