Belvoirdale sells one they have made in England. Do a google and you will find them. Partidge used to make one called the Ken Baker Streamer Hook, but Mustad (who bought Partridge a few years ago) discontinued it, you might be able to find some though. I'd go with the Belvoidale hook.
My favorite streamer hook is the Dick Talleur hook of Daichii. Even though it is bronze, it has a finely tapered loop eye, is 7X long, and has a beautiful modified Limerick bend.
I almost forgot, Daichii also makes the J171, which is black, tapered loop down eye, 6X long, and Limerick bend. The down side, it is only offered in #1 and #2.
