14 mm S/S Thimble. Where to buy?

I have ordered a 10 kg Flook and 14mm nylon for my second anchor. Need a thimble. Prefer S/S.
Tried Whitworth Marine, and a few others. They only have galvanized in anything bigger the 12 mm or 1/2".

This going to be my second anchor.
The makers recommend nylon and no chain.

It's hand deployed and retrieved which also suits my need for a back up anchor if the winch fails.
I did find 14 mm thimbles at the BCF store on ebay but now know I don't need s/s.
Appreciate your help. Thanks.
