I "bit the Bullet" and put them on my Burton Bike Bits order, at least they are NOS, English-made. They were "only" 88GBP each which is apparently a good price.
I did find an ebay UK seller who recaged Chinese bearings to work but they were 50GBP and there is NO WAY I would buy Chinese Bearings!
There used to be a Timkens made but they seemed to have gone away.
