Toms Turnstile (original brass)

A modern-day classic, Tom's Turnstile is a great pocket-sized sequential movement puzzle where you need to arrange the 12 brass numbers into order. Making this difficult is that there are two rotating wheels that each have to contain 2 numbers each and are connected by cogs, so as one turns clockwise the other turns anti-clockwise.

The puzzle is make from brass, which gives it a great feel and wonderful weight, though it does start to look its age quite quickly. There are still a few available in some stockists, but mostly these are getting very, very difficult to find.
