I have several hubs I could help you out with, along with wingnuts I can add. But as I've so many it would be quite a faff to photograph them all and let you choose, so if you could give a better idea of what would suit you best it would help. Such as if you'd prefer something period correct to suit your project, if you'd be interested in NOS, high flange or small flange, alloy or steel (possibly both with the really old hubs), painted or chromed/polished etc.
