I might be interersted in that hub its_kirby
The Gen 1 hope Hub had the fat centre, there was a Gen 1.5 which had a fat centre but the push in adaptors before the Gen 2 which had a thinner centre and push in adaptors
My Gen 1's run a top hat affair that sit against the bearing but I've owned Gen 1.5's with the push in adaptors and you would be hard pressed to tell them apart from the bulb ones
Wish I'd taken pics / kept them now!
