Looking for more info on a Mares Frontiersman

[trfollis]

I recently came across 2 large dive bags of a ton of vintage dive stuff being thrown away and in the bottom of 1 of the bags were 2 spear guns And 1 is a Mares Frontiersman. The only info i can find online is for recall information from 1979. If someone knows where to find more info (manuals) on it or what its worth, please let me know.
