Sorry for late reply,
thank you for your input Ex Brat and ericmunk i will look into both avenues suggested now im back with my keyboard.

Would anyone else have suggestions in regard to the tyre sizes wheels etc?
I would imagine if they were post War that they would be early going by the Air Ministry marking that is located on one of the tyres.

I have 2 of these wheels that are joined by means of a wooden structure you can see this on the Facebook page (Factory stamps WW2) if you would like to see a photo.

Any help would be appreciated as always.
