While I do not doubt what you say about different moulds and families I took another look at both hooks in the flesh and I am struggling to to see a difference and certainly nothing I would describe as "very obvious".
In your massivly magnifed photo in the post above it appears (for example) the hook on the right possibly has a very slightly larger shank & gape. However even the angle of the camera can distort things with tiny details like this. Also its important to note that both hooks are offset to the left so that can also distort a image as the hooks dont lie perfectly flat.
Take a look at the photos below. I have attempted to compare shank and gape. Perhaps I am blind but I cannot see a "very obvious" difference even in this massivly magnified photo.
Also important to note at this level of detail even the SAME hooks varied very slightly ..some of the hooks from the same packet having very slightly more barb for example. Nothing will ever be -
exactly- the same
Again I stress I do not doubt what you say about them being differnt models but from a practical angling point of view -at least for me- I will continue to see them as basically the "same" hook in different Strengths/wire guages & as I said a few posts back..a picture paints a thousand words so people can decide for themselves.
