 * Set of Franklin Railway Supply Co. Inc. fire doors found in a Chino, Calif. antique shop during the late 1970's. I did not know the importance of these fire doors until I wire-brushed them clean and the center-punched numbers 3752 appeared on the lower left door half.


 * I later found out that these doors were removed when this particular Santa Fe 3751 series engine was converted from coal to oil in San Bernardino shops in 1938. The center-punched numbers were meant for replacement to this locomotive if the conversion failed. This particular 3751 class engine was placed into service in 1928 and retired in 1959. The 3752 was the first 3751 series engines ordered after the success of the earlier 3751 experimental 4-8-4 prototype.
