Since Mustad has changed the numbers on their hooks, does anyone know if they have published a list of some sort indicating which of the new numbers will correspond to the old hooks or are the hooks themselves completely changed too?

I hit a problem today when checking an old pattern and found that the hook in the pattern did not match up with descriptions in Mustad's new hook listings. It used to be that if I did not have a mustad hook I at least could find a substitute hook by another manufacturer.

What corresponds with the old 3906B ?
