An unmolested airbox is a rare and valuable part Malcolm!
It is unusual to find them with their captive fixing nuts in place. All too often the bolts seize in and result in the nuts turning in the airbox and breaking the plastic housing - not the best design!
Also, snorkels get cut or removed completely and then lost.
I did manage to find the other airbox! It is also intact complete with full snorkel and no drilled airholes. Although one captive nut is missing. In general the airbox is a little scuffed but fully functional.
