A retro or vintage Mettoy clockwork or wind up train as per photos. I do not know how old it is but likely 1930s - 50s ?? Looks quite neat. I understand that Mettoy were a rival to Hornby in England. Anyway, there you go. I have wound it up and it does go (but do not have tracks etc to put it on so do not really know how well it goes and distances on trackes etc) And I do not know gauges, but am guessing !!! gauge 0. Distance between outside of wheel rims is approx 42mm, and inside of wheel rims is approx 24mm odd, and the inside from where the flat of the rim (where it rolls on the tracks) to the start of the highest bit of the wheel rim that would sit on the outside of the track is approx 32mm. So, from that, anyone who is into these should know, or be able to work out the true gauge easily. Now, to me, & I am not a train buff, it looks reasonably good for its age. Has scrapes marks, paint wear, chips etc, but to me its basically fine for what it is. It is bent a little out of shape just behind the rear two big wheels, needs to be straightened there. I have taken photos to try & show that. There are a lot of photos, so should be enough to give you a good general idea. The brake inside the cab works. It measures approx 150mm long x 50mm odd wide not counting the key, and approx 75mm odd high.
