I, too, agree: SP System B-50-14 or B-50-14A. The former were built 1924 by SSC. Starting about 1932 most were rebuilt to Dreadnaught square corner 4-5 ends. Those that also got new bolsters and draft gear were classed B-50-14A. The ends did NOT have a reverse stamping in the upper panel, just the usual. Other photos of both the A and B ends of SLG&W 108 and SP System cars show that is so when the lighting is better. Many small details of rivet patterns confirm the rebuilt B-50-14 / -14A origin for #108. The cars were built with three kinds of roofs: early Viking, Hutchins Dry Lading, and Murphy Radial. Photos of #108 remove series with Murphy Radial from consideration. I'm not confident guessing between Viking or Hutchins based of the photos available to me. The outboard "bolt" on the seam caps seems rather more prominent than on a Hutchins Dry Lading perhaps indicating Viking? The 1956+ SP system-wide renumbering the remaining cars were renumbered into SP 111171-111534. The ORER indicates 182 of these cars in 10-1960. There
It is possible that #108 came to the
SLG&W any time from the 1939 on. There are increases in the ORER box car count in 1939 (0 to 2), 1956 (1 to 2), between 1956 and 1958 (2 to 3) that may be clues. The earliest dated photos of #108 are 1960.
