This may be a long shot, but why not- There were only 25 of these made when they were available, and I'm wondering if anyone here has one and could post pics.
It's been awhile since I've hung out over at the bikerscout.net boards, but I do remember many use/replaced their regular vynl DP helms or fiberglass castings of the regular DP's with carriage bolts at the visor hinge point. Some used the flat top ones & added a plastic cap over it or just used the domed ones and painted them. Army Scout over there may even know or have good reference material on limited FG DP Scout lids.
I think you would have no problom selling a good amount of these... I would also post an interest thread over at Bikerscout.net as well. Not every one over there is a member here. I would think anyone knowing the origons of this helmet would be happy to buy one.
