The double-door car NP 38332 you ask about is from a series leased from AA Morrison beyond the STMFC period (1962) as shown on the NP Freight Equipment diagram #53. The diagram, linked below, states that those cars were built during 1944 and 1945, but they were not on the NP until the lease date.

The NP had double-door steel sheathed cars in the 1950s; they were plug+sliding door types, with nominally 6 foot sliding doors. See, for example, diagram #24 for cars built by NP in 1958.
