Mystery WWII tail wheel and tyre ?

More information of where the pictures were taken and the circumstances might throw some light on the type of aircraft although a Meteor nose wheel seems to fit the bill.

Was this taken from a ‘dig; a scrap yard or ploughed up locally ?

Thank you for all your reply’s and help. Really informative and much appreciated

Yes the photo is a Mk IV

Fair point. It would be an early one then.

Meteor nose wheel tyre.

Chunky tyre tread for a nose wheel?

After thinking about it more I believe its a good match for a Meteor nose leg fork, the main is similar but beefier. 

I do wonder if it is actually part of a main undercarriage leg, in the first image is that a steel brake drum liner inside the remains of the mag alloy wheel. It also has fittings for attaching a mudguard, spat or fairing so potentially/maybe a fixed gear type.
