Old Capco Surface Grinder restoration!

[Ancient-Axeman]

Hello All
Please excuse me for not sticking purely on a CNC topic.
Six months ago I bought an old Capco surface grinder that was converted into an improvised vertical mill.
Hoping to restore it into use as a surface grinder.
Yet to find a picture of this exact model so far and am struggling to source information regarding rebuilding the headset.
I will attach some photos to illustrate my quandry.
I thought taper roller bearing would be needed but both bearing seats face the same direction.
The spindle I will need to make or get made, have no idea what diameter and type of attachment the wheel will need [ either a locking nut or hub with a morse taper?]
The motor sits inside the casing and drives the spindle internally.
I even have the original drive belt made of material with a metal hinge!
Would love to get any thoughts on this, feel free to tell me what you think!
Cheers
