First, go here and scroll down to see what a real one does
look like:

The 'heads up' that it's some kind of copy is the very
rough interior of your helmet. Yet, that seems to be due
to the liner being removed.
Also, the rangefinder and stalk is not right for the Don Post Deluxe's
I have seen. You'll see it in the photo on the above webpage too.
This could be 'overthinking' on my part as they may have had diffrent
'runs' on this part and they could vary.
Lastly, the visor area doesn't look quite right. But i'm not
an expert on that. Having dealt with couple of fraudulent items
before in ebay purchases, paypal has always refunded my money.
Paypal seems more aggressive in helping than ebay (though I think
ebay owns paypal now).
While perhaps not a Don Post Deluxe ( if it is a Deluxe, I have no idea why
anyone would repaint it as this one is not an improvment on the original
paint), it does appear to be a nicely made, perhaps fan made, helmet. If it
is a Don Post, they really needed to inform you that it had been heavily modified from the original. You could expect to get $100-200 in a competitive auction. My guess is the closer to Halloween, the better the price may be.
