Definitely steel 'toons w/ adjusters. I'm thinking it's the camera angle (and jumped rollers) that are hiding the one on the front nose. They must have been pretty loose to get the rollers to jump off the top rail.
There must be some serious forces at work to have that many jumped rollers, and still have the one circled in the pic pulled up like that.
No powder to fight off in Pennsylvania- That snorkel is there to feed the fresh cold air charge to the massive turbo trying to poke itself out thru the side of the engine panel! That's what the mystery bump is!
All good for forcing out 375HP.
But, everyone has missed the reason for the $24k price tag. It's the weight saving Prototype L/H Rear Pontoon. Apparently, during his 'rebuild', he deemed the pontoons just too damned heavy. So, what better way to shave weight than to just skip welding the skin back on the pontoon. After all, it's on the trailing edge, so it won't pack itself full of snow. Very innovative.
