'92 RockHopper Shimano hub axle sizes

Retro Newbie
Were original '92-era Shimano axles supposed to be 9 or 10mm diam?

The reason I ask is that my current wheels and hubs now are non-standard, not even Shimano- Weinman 519. They are 9mm diam axles. I don't have access to the Shimano hubs I plan to use so I can measure them.......

I'm going to have the local Bike Man build two entirely new wheels:
<>New Old Stock Shimano hubs ('92): HB-RM50 front, FH-HG-50 rear
<>NOS Shimano Hyperglide 13t to 28t cassette
<>Velocity Aeroheat 26" 36-h front and rear rims
<>WheelMaster black stainless spoke sets both 36-h
<>WheelMaster 4130 front and rear axle assemblies, hollow for QD system

Speaking of which, what size WheelMaster axles should I use?? That's really the bottom line, since the Shimano axles that come with the NOS hubs will be replaced with the new WheelMaster axles........

And any recommendations for super-high quality aftermarket skewers for said WheelMaster axles? I don't even know what the diameter of the skewer rod is supposed to be!

After the wheel-building is complete, the bike gets paired with a new BOB Yak trailer to carry my backpack.

Thanks!!
 
Re:

No reason other than I want an identical spare set of axles to do some machining work on them (modifications)

I'm sure the original New Old Stock Shimano axles are just fine for quality.

WheelMaster doesn't make it easy to find the axles I need, the tech descriptions are pretty damned vague.

Very strange indeed: the drop-out slots for the rear axle are also 9mm nominal diameter.......

How was a FH-HG50 hub ever attached to this frame?
