Pretty unusual item. The Taylors used to make a trike with two wheels at the front. These are the front hubs used to make these trikes. They have stub axles and were seemingly supplied by "Rousson& Chamoux", Loire, France.
$20 per pair, plus post at cost.
If any one needs Higgins trike hubs, I have these two, NOS, $20 per pair.
