Ian..IMO even without a liner its worth that ! these cammo helmets are climbing in price, high prices at that....the liner could be a replacement or not I would need closer photos especially of the rear of the liner pads to determine. I have just sold my M17 with original Cammo paint to a good collector friend, it was a shell with the original pins and liner band...I sold it for £350 ! a dealer price could be near double that these days !
Prost ! Steve.
