Here's a recently acquired postwar Hornby clockwork set:
The 2270 locomotive was manufactured during both the pre- and postwar periods. As I understand it, they are very similar in construction, one difference being the prewar version having red spoked wheels. This one is likely from the early to mid-1950s.
Let's see your O-gauge Hornby gear!

So fascinated with thee clockwork trains---and even more amazing that some of them still work

Yup, after all of these years, the mechanisms can be pretty fragile. One has to be especially careful not to overwind. Fortunately, all three examples I have are still in running order, although the Marklin is a bit dodgy. There was a time when finding a key to fit was a problem, but those are plentiful now.
