I first saw an ad for this stooge in Stunt News probably 25 years ago. It was priced around $100.00 I think. Like probably many others I was put back a bit on the price. Somewhere I did get to see one of these stooges. It was made by or for Bob Barron. When I saw the quality of this stooge, I decided it was really reasonably priced. I called Bob Barron to order one of these stooges. He told me they were no longer available as the response was so poor, he had discontinued making them. What he did tell me was that if I was going to fly with a stooge, "DO NOT DO IT HALF A$$ED". "DO NOT ATTACH THE STOOGE TO THE TAILWHEEL STRUT". Yeah, I know, you have all seen or done the little loop soldered to the tail wheel strut. He then explained to us a separate tail hook built into the model and dedicated to the use of a stooge. Since I myself had experienced tail wheel strut failures, I took Bob's advice to heart. I make a separate tail hook made from .078 music wire and the installation varies depending if installed during construction of the model or if retrofitted on a completed model.
One time at contest many years ago I was flying a model that had been retrofitted with the dedicated tail hook and during a practice flight the tailwheel strut, 1/16 wire, broke off where it exited the fuselage bottom skin. I used the stooge hook as a tail skid and completed my flights. True story!
One parting comment, anyone who thinks this stooge can be made with the average tools most modelers have available has gone around the bend a bit.
