c1950s pressed steel winchester rifle cork gun

I would have killed for one of these as a kid!
A wonderful vintage large pressed steel cowboy Winchester toy rifle which fires corks.
It has a gold coloured diecast trigger handle which is engraved with a pattern.
The plastic butt has a horses head on one side and a buffalo on the other.
There is a small hole just above the hand grip for putting oil in.
The gun is undamaged and still works a treat.
Just a bit of tarnishing on the hand grip.
It is approximately 32" long.
