Wheel diameter for YOB crane

[Mancunian]

I'd be most grateful if anyone knows the wheel diameter for this machine.
The EFE model has them as 13.13mm which isn't a size I recognise. It certainly isn't in the AGW range.

I assume that you're looking to rewheel for EM or P4? That scales to 1000mm (i.e., 1 metre), which makes sense for an Austrian design. The closest in the Gibson range would be for a Warship (so 3' 2") which is 12.5mm or thereabouts. Could you live with a 12mm disc and a washer to sort the ride height out?

Yes, the idea is to re-wheel for P4. I've currently fitted 14mm plain disc wheels (4005) just to see. There're not too bad actually but I will follow up on your suggestion for the Warship wheels, hadn't thought of that.
I can recommend the model, it's a beauty.
