Suits Rileys from 1930s. Falcon and similar.

Used. All bar one for the nearside, only one, Riley branded, for the offside.

160mm across ears, 30mm deep, approx.

Thread internal diameter 54mm.

Five marked Riley, one unmarked.

Approx 490g each, one at 580g and another 645g approx.

I don't know whether these Rileys only ever used one thread for the hubs, but I can measure thread pitch if you require. You'll be sure of your application then. Irrelevant if these are just to be used as jolly good paperweights.
