I spoke with Bill Stevenson cyclist racer/tandem and frame builder, took the wheels buy his shop and he had heard of the silver Arai brake but had actually never seen one...

Yes they are the spin on threaded hubs the front has thread on one side and the rear has thread on both sides (a flip flop hub)
