I found these two photos, from the June 1973 Frisco Modelers Information Group (FMIG) meeting in Springfield, MO in my files yesterday. Photographer unknown. Doug Edit 5/11/2024: Caboose SLSF 1303 - On the east end caboose track, adjacent to the diesel parts storeroom, Springfield, MO. Note how when the car was renumbered in 1968, the added digit 1 on the end was squeezed in between the door frame and the originally centered car number 303. The car is coupled to caboose SLSF 1312. Caboose SLSF 1323 - On the east end caboose track, Springfield, MO. Note the stacked lettering on the flat car side sill, "Springfield Terminal Only". Added photograph narratives and location of photographs. MKD
