Yes, this is former Tonopah #1 so second #1 on the SVRy roster. The two sets of new cars that the RPO is from came in 1918, so the photo is after that. #1 got a Rushton stack in 1927, so that would give us the date range of 1918 to 1927. I am thinking that this might be at Austin. #1 (2nd) was a big mogul with 17,184lbs. of TE. While #1 was scrapped in 1934, the tender trucks and frame still exist at our McEwen yard. They were used to make a narrow gauge to standard gauge idler car.
