I just checked out the thread as you suggested, and found an actual photo of a Penncrest model A-131 in the same color. The thread can be found in the 2007 archives and is loaded with information. The Penncrest photo's can be seen in reply numbers 97, 98, and 99, where a tag dating the machine to 1966 can be seen, so yes, it's an older machine. That makes me wonder how many years that body was used, and how many different models used it?
