Perhaps you have had success by now, but if not, keep an eye on eBay. They come up every once in a while. For what it is worth, Yuengling had K-line produce two different cabooses, one for their original series in 1990 which just had the Yuengling name on it and a second one for their "Signature Series" set in 1997, which had the Yuengling Porter logo on it. The Signature Series one is a lot easier to find. There were only around 500 of the original ones made in 1990, so they are tough to find. Good luck!
