Wire wheel lug nuts

I picked up a set of wire wheels for the Ruby project and was short a couple of lug nut adaptors to switch between 4 1/2" and 4 3/4" bolt pattern. The only marking is an arrow on the inner piece that shows orientation toward the center or away from it. The wheel hole is round and has a depression to accept the washer.
The one wheel center has what looks like an "A", but cannot find any other ID marks on the wheels. They are tubeless so I expect they are newer wheels.
Does anyone recognize them?

 

I think I found the answer in a 2014 HAMB thread. Appliance is the name that comes up with a three piece lug.

 

Appliance Roto lugs is what they were called, I think there may be some modern replacements

 

I think the modern upgrade is bushings and you use regular lug nuts
