It's die cast, monkey metal or something like that.
Stencilled with 'Made in Denmark' on the back.
At a pure guess I would say 50's or 60's.
Chance find a few days ago on eBay, thought someone would outbid me, I put a single bid in 5 seconds from the end of the auction (as usual) and got it for £28.
Just bought it for a desk ornament really!
That's all I know 
PS – the clock is important as well, I want one of those too!!
