I'd say go with what ya fancy...you can always change wheels later if a pic turns up to show you used the wrong type. (50% chance of getting it right!)
Well, 210003 was the 3rd Dora produced so it is more likely to have had the tread tyres, i don't recall in any of the dora books that this aircraft had a tyre change...But when it was recamouflaged in feb 45? i think? the canopy was changed from the early flat to the later bulged type....it is always possible that as the longest serving Dora from Sept 44 to May 45 it could have had a tyre change but it is still a 50/50 call on which type.
