I had one called the Howatt TD. One sweet bow which I only sold because I went lefty. It was the forerunner of the Martin TD and the Hatfield. But I preferred it to either of the last two named bows. The guy I sold it to is still shooting it. Howatt also made the same bow for Doug Kittrege and called it the Backpacker TD, East Side Archery in Chicago called it the Nimrod TD, and Jim Dougherty Archery called it the Alpine TD I think. All the very same bow just a different name on it for the various shops that sold it. There should be a lot of them out there but I absolutely never see one for sale. It had a knurled thumb knob limb bolt that was rounded somewhat on top and no tools were needed to take it apart.
