I have one of each major type of the large sheet metal 944 type engine, except the red one. Only seen one or two for sale in all my years of watching, so odds of getting one are pretty slim. Looking at the photo of an original, it appears darker than most Marx reds so I used a different red than I usually do. The inside of the frame and shell are well marked to warn folks it is an imposter. Next is the NKP red tender. This will have to do as place holders while the search continues.
