Hope QR adaptor

Can any member tell me what Hope front hub this QR adaptor is for. It unscrews at one end by using 2 x 5mm allan keys.

Hope Big 'Un if I recall correctly

Re:

I've never owned a Big Un hub but did use it on one of my Hope disc hubs, now gone. Just can't remember which hub it was. So any other suggestions. Bulb perhaps?

Could be for any of the Hope hubs which can be adapted to 20mm, Big un, Bulb, Hope pro series etc. I've got a few of them and they're all slightly different widths, which is infuriating trying to find the right one when I want to put a 20mm thru-axle wheel in my truing stand.

Its for a bulb
Is the spacer on the other side(the flange bit) is the same length ie identical on both sides, then its a first generation bulb(5 bolt) QR adaptor
Should one side extend out a bit then its for the 2nd generation bulb(6 bolt)

Runs off to retrieve pic

Pics from top:
1. BULB 2nd and a bit or somewhere between the 5 and 6 bolt.
Its different in that the flanges interface with the bearings at an angle. Ive no idea of why its different.
2. Standard modern 6 bolt bulb
3. 1st generation 5 bolt bolt bulb
4. Big UN 25mm qr axle

Bulb 5 bolt hubs and 6 bolt hub QR axles arent interchangeable. Only the correct one fits the other doesnt.
