OK, got a small item to contribute.
Recently I got an axle set (axle/cones/spacers/washer/locknuts) for a Shimano HB-M475 hub.
I don’t own the hub, and probably never will. But getting the locknuts separately – which are thin 10mm x 1mm locknuts that are only 3mm thick – would actually have been more expensive than ordering the axle set. I wanted the locknuts.
I’m keeping the locknuts and spacer washers. The cones and axle are up for grabs. Shimano EV for the hub can be found at

This is one of Shimano’s 10mm QR front axles for 100mm OLD hubs; I’m pretty sure it fits standard front dropouts. I think – but I am not positive – that the axle will fit other similar Shimano front hubs of that era that use such an axle. However, based on perusing Shimano EVs, I think that the cones are probably unique to the HB-M475 (though they might be usable in a pinch with other front hubs using a 10mm axle when using suitable spacers and/or alternate seals).
PM me if you want the axle and cones. First come, first serve.
