If you are looking for large format drawings that "show all", you might search your roster for cars that were built by either Pullman or Haskell & Barker, then contact the Pullman Library at the Illinois Railway Museum :https://www.irm.org/pullmanlibrary/

It's easiest to find drawings by builders lot number, but possible by road and date. 1901 is a bit early for the collection, but just about every freightcar produced after 1909 will have some information. Each lot typically has a 1" scale general arrangement drawing (the format typically presented in the Car Builder's Cyc's), a separate 1" scale drawing of the underframe, another of "steel details", and multiple smaller large scale drawings of component parts, sometimes including trucks. Occasionally there is a lettering arrangement drawing. The large scale drawings can be ungainly to work with, and I find it easier to order them at 50% reduction and use a magnifying glass to read the smallest dimensions; the sheets are still completely legible at this size, but the total sheet size is reduced to about 2' x 3'.

The reproduction fees nay seem a bit high at the onset, but the wealth of information is worth the price.
