Yep, highcountry is right (he should be, he has a boatload of them
). There are a few black on black ones, I've heard special order or later in Jack's career when he was running out of higher wt white glass, not sure which, or maybe both. One was on e8ay a while back, black on black, didn't sell at reserve.
Jack also sold a "Howard Hunting Bow" which were simply Howatt Hunters that he bought rough and finished himself as a lower cost option, they were 62 inch, like all howatt hunters.
He also made a couple or three versions of Gamemaster bows (not "jet"). As well as a target bow that is extremely rare.
I don't know about the comparison to limb profile on Hunters, I've compared limb profiles and observed significant differences, but I've only looked closely at maybe 10 howatt hunters in this way, so maybe there were changes over the years... I'd be interested to see pic overlays of the Howatt with the same profile as Jack's Jet. Certainly the Jets are 66 vs Howatt hunter 62 inch, and have vastly different profiles at full draw.
I love the '70s hyperbole in Jack's ads, but the Jet isn't "world's fastest bow"
. I've chronyed Jets, and probably a dozen bigger name recurves and really don't see more than a few fps apples to apples comparison... as everyone I've talked with that impartially has done similar crony tests of better quality recurves. That said, Jacks bows don't take fast flite, and still compare to the rest. In reality you see very few bowyers trying to advertise by differentiation in speed anymore... pretty much everyone agrees that the "magic bean" for speed/performance is either imaginary, or compromises other aspects of shootability.
What his bows do have is a really great compromise of performance and "shootability"....this is something a lot of the bowyers influenced by target archery were or are able to maintain. My favorite aspect of the Jet is the grip - you'll either love it or hate it, but for myself I've never shot or handled a bow with a better.
Jack was a character, and he made some enemies over the years. He is a legend, too, and was quite a pioneer in his day. He built something around 1000 Jet bows, as I understand, and over the years I'm sure the existing number is quite a bit less... it is known that quite a few were broken early in the fast flite days by guys shooting them with FF, for instance. For the fans of his bows, the fit/finish, shootability, beauty, and legend of these bows is second to none. There have been, and are, hundreds, or thousands of "full time" traditional bowyers out there. A handful will be remembered after they are gone.... Jack is one of those guys.
