Proteam solid front axle size/dimensions

[David Healy]

I have a Proteam folding bike, and it needs a new front axle, but nobody can establish the size for me!!!
I can not recommend this model, as I can not find contact details , for the manufacturing company, anywhere online!!
It’s so frustrating that I’m about to take it to the tip!!
Can anyone please tell me the axle size?????
