Vintage Racing Kayak, Prijon Mithril 4.5m Lx60cm W. K1 Kayak?

My research has me thinking its a prijon interceptor or prijon 420???. I got this kayak hoping to use it with the kids, but it's past my skill level. It's 4.5m long and 60cm wide and only weighs 11.1kg. (14'9"L 24.4lbs). It has the Kevlar markings and a golden hue finish inside which my research suggests it's one of the first brand kayaks to be made using carbon/Kevlar ?.

Do your own research or arrange to view the kayak, it's in Rutherford nsw. I think Prijon HiPP industrial Mithril Kayaks Hingham MA are the makers, they made competitive USCA downriver racers in the 1970s Behind the seat is a nationals marking and still has race no 601 on it. Do your own research and message me if you want more photos or info.
