I am the one that Mike (Xinumike) referrered to, about drawings for D&RG c-21. I am a 30+ Member of the St. Croix Railroad and have constructed three engines that I run there. A NG 2 cylinder 2 truck Shay, 1-1/2" scale for 4-3/4 inch gauge. A NG Mogul, "Trish", also 1-1/2" scale for 4-3/4" gauge, and a Little River, 2-4-4-2 articulated Mallet in 1 inch scale. Most resent.
I am mostly interested in Colorado NG, mainly the DSP&P. My Mogul resembles DSP&P #5. See article in LSORR, July - Aug. 2011. I have a complete shop in my basement where I built these engins.
As I am new to this group, refer to me as Fred. Thanks
