In Reply to: 12 holes in wheel center? posted by Tom on January 16, 2018 at 20:00:08:
Early 28" & 32" were that way. Both very early rims had the cast lugs, later the hat rims. I also have one 28" center disk with 12 holes. One set of 6 holes has a slight flat along the outer diameter. I would assume to allow clearance for the cast lugs.
If anyone wants/needs a 28" center disk with 12 holes, let me know.
