Thanks Bryan, looked up. They don't mention what make they are and including shipment I get to 51,08 £
Same as other ebay sales with 44 plus postage.
EDIT: oops postage 16.50 £ there, no thank you
An inquiry to the above ebay Korean bearing sales result:
They only ship batches of min 10 pcs abroad. (My F would have only needs for 4 )
Anyway, I'm not in a hurry.
