Camberwick Wind-Up Figures
Trumptonalia.
A set of 3 wind-up,clockwork toys produced by "MM Toys" in 1966.

I believe "MM Toys" may have had something to do with Louis Marx of Swansea,but I could be wrong.
And you'll often see these sorts of wind-up walking figures described as "ramp walkers" [or "rampwalkers"]

Made of plastic,they're each about 15cm tall.And pictured below are the full set of 3 produced :- 
Captain Snort ... Windy ... and PC McGarry.

All from Camberwick of course.
And they certainly played it safe too,because these are arguably the 3 main characters from the series.

The photos were rescued from an old ebay listing and,for some reason,I didn't take a note of how they were described.

But you'd have to imagine there's a very good chance they were ex-shop stock judging by the condition of both box and toy,nevermind the inclusion of the original plastic bag for the key.
Either way,a cracking little buy for someone and a rare opportunity for us,because even unboxed examples aren't that easy to find.
