Here's what I know about it:
9 quarter inch ball bearings on each end
135qr
Formula hub (or so I'm told by the previous owner)
Photos:
TIA.
No, but it might be for more than one, Formula made hubs for other people too, Diatech for example were rebounded Formulas
Are you wanting to replace it? Cones pitted?
If so just buy a weldtite equivalent and put those top hat seals on the new cones with correct amount of spacers to match old axles dimensions. ...
Yes the cone is pitted. It doesn't look like the one that is pitted (on the right in both photos, NDS) will come apart and there are no top hat seals. The other side does have a top hat seal.

By top hat I meant those things the axle is resting on in the pictures. I guess they are shields rather than seals.
In my experience they usually separate from the cones. Balance them between a vice, resting on the shields and you can tap the cone out. The shields then fit over your new cones.
I may be wrong though and they are one piece but I've done this many times with axles that look like that.
Have a look here and then Google the part no for the matching cone.
Not cheap, and not all available in the UK, but far better than the OEM ones.

Maybe worth it assuming the corresponding bearing surface in the hub isn’t similarly damaged.
