I'm assuming you're refering to the photo of the right side of 375 at Farmington. The original print post card sized print had no info written on it but looks like the typical work of M.P. Moran of Farmington during 1932-34. It appears to have the flat smokebox front.
375 with the long bright smokebox at Durango also had no info on the 616 size print but is likely 1929 - 30.
