|Located at 1313 S. Bristol Ave., Tucson, AZ. There is one 7 of the road number visible in some of the other pictures I have. This MAY be SP caboose C30-1 road number 378; a one-of-a-kind pilot rebuild done at LA General Shops in 1957. See page 134 of the book SOUTHERN PACIFIC FREIGHT CARS Vol. 2 CABOOSES by Tony Thompson for more information.
