I can just see him at the work bench of a winter day, big bronze soldering iron in hand making the derrick. That it survived is amazing, considering the time, and the people that have been in and out around there. The toy truck he used, is an AC Mack! probably just a ten cent toy when he made this, but wouldn't mind having one at all. Plus on the base, the engine he mocked up to provide power, is an early T head 4 cylinder, not sure I've ever seen a model of one, or one in a model. This was sort of like waiting for you all these years wasn't it?
