John:

To the best of my knowledge those Tiemco 518 size 32 hooks are still available. Tiemco also still shows them on their website. I hope so because I use them all the time.

There was an even SMALLER size 32; a true proportional size 32 that make those Tiemco 518's seem huge. It was the now defunct Mustad 277 that was so small it had no eye! It has been discontinued for years. Partridge also had a size 32 Vince Marinaro hook that was about the size of the 518 but with a down eye and a longer shank.
