This large hub is fashioned after the military hub, referred to as the Archibald hub. It will fit the 2” and larger axles and requires a 2” to 2½” spoke. Unlike the lighter roller bearing hubs, these do not have mortises for the spokes to fit in to. This is an extremely strong hub and often used on larger coaches and hitch wagons. It is machined to take the large 12” hydraulic drum brake and has a very nicely machined brass hub cap.
