Okay this is probably a bit of an odd question but can anyone telll me the overall outer diameter of the wheels on MiniArt's Farm Cart, this one here :

Hello Dean mate ,, well you helped me out with the barrel for the Sherman Frail on the Crossing the gap dio and now its that dio which is going to help you out
Strange how that worked out huh ?
Righto then heres the stuff you need, the wheel measurement is 39.51mm , it is stuck to the base tho with resin but after quite a few tries this measurement came up the most .

Thanks for that, I need two wagon wheels with a 40.5mm diameter and that's close enough for me. Once I run some .5mm plastic strip around the outside they'll be spot on. So a shopping I will go.
