Im afraid you may be correct on that point, its a shame because it looks halfway decent, i wondered why you didnt post the side skirt for the mnftr,
Chris i dont think its worth that sort of money, especially as theres doubt over the originality, as much as id like to say go for it i think i would walk away on this one if you cant see any mnftrs stamps
If real and with the amount of liner damage i would think $250 is a reasonable price, are there any markings on the liner or have you not seen the helmet in person yet
Well its got to be a hands on inspection then, you can only be the one who can judge this one, i hope it turns out ok for you, but im still doubtful, good luck mate
What is the sellers inspection/return policy? If no returns then I'd definitely walk away. But if he allows a certain number of days for inspection/return and shipping isn't a killer you might consider it so you can inspect the helmet in person.
Does he offer any guarantee? If a dealer then most reputable dealers will be happy to offer a guarantee, at times lifetime that a piece is original.
