This is the old school type Zuffenhaus solid hub that isn't made any more. All of the modern hub extenders have the accordion look and the solid look is so sought after that a sleeve is sold to make them look solid. It will accommodate a 5-hole or 6-hole (Momo) steering wheel. Hubs today are available mostly in 60mm or 80mm so this extends more.
Looks new and maybe it is.
