Does anyone know what these were? 1926 photo. KO nut has "left side" and "on" with an arrow cast into it. Anyone have a source?
Judging by what appears to be a stock Ford rear wishbone I will assume that this wheel is mounted on a stock "T" rear axle. Available pin drive wheel brands for a "T" were Pasco, Dayton, and Houk. The Pasco wheel nut is much larger than the one pictured. The pin drive Dayton and Houk wheel centers are almost identical in appearance. Almost all knock-off type wheel hubs use left hand threads on the right side, and right threads on the left... Except for Dayton. The hub cap on this wheel clearly reads left side and the arrow seems to indicate right hand threads. That being said I would say #3 Houk.
