The Fawcett book - the reprinted one that is because the pictures are better! I used to have a copy of the Pruett one and would buy another if I saw one. There are two photo's of the Baldwins one dated 1956 and the other is undated but shows the locomotive #103 with a two tone stripe along the boiler, cab & tender.... Looking through another generally photographic book which deals with the Central of Peru & Cerro de Pasco states Baldwin 2-6-0 # 3 later #103 shown in a picture thought to be 1930's. Hunslet #107 was, I think, built for the FC Trujillo (very dubious spelling).
