The tender in the Alamosa dead line is an older flared tender with the double row of rivets. The other pictures show the winged tender it had until scrapped. I would guess these pictures were taken soon after the 207 was overhauled in June of 1923. It had new flues installed at that time. The loco was used heavily the rest of 1923 and 1924. It sat out of service for the beginning of 1925, not being used until October, November and December. Stock rush maybe? It was out of service in 1926, only being used one day each in March, April, May and June. It was scrapped in October 1926. Leased June, September and October of 1924. Probably to the RGS but could have been on the lumber lines.
