Ive got Sturmey Archer hubs in 20 28 36 and 40 hole
the 40 hole was common on the roadster bikes.
the 28 hole hubs are on 20" wheeled shopper bikes
and the 20 hole hub I got on a kids 16" wheeled bike. Now rebuilt into a 16" alloy rim for my RSW

I said to use old hubs as newer ones might be wider. Especially the shimano ones
