Bearings! Or lack thereof...

I thought the front wheel of the roadster was a bit on the piss, so I took the cone spanner to it, and lo-and-behold I’m missing a bearing… it’s just not there. A gap where there should be a whole bearing.

So now I’m going on the hunt to find loose bearings. My local shop only sells races & cages, so I’m going to have to look further afield. Where does one buy bearings for a 25 year old hub?
