I had a similar problem, I 'inherited' a large collection of Mustad hooks that were sorted into indivdual containers but not labeled. I was having a heck of a time trying to sort them out.
I was able to order a catalog from the manufactor that had a 1:1 scale image of each hook size and shape. This has helped me considerably. I think most manufactors have such catalogs, intended for a reseller or fly shop, not the general public.
