My sense (no data) is that, at least in the northeast, the rebuilding of 36-ft box-cars constructed ca 1906-1914 was continuing unabated through the 1920s.
This was certainly the case with the NYC system. At the turn of the twentieth century they were building 36' boxcars with truss rod wood underframes; about 1910 they adapted the same design to SUF, then almost immediately started rebuilding the earlier cars with several designs of retrofit SUF. Found several drawings in the Pullman Library of the underframes when researching the cars that were the prototype for the Accurail model. Some of these earlier cars were about 1'-6" shorter and the underframes were built to fit that shorter length. By WWI the rebuilding was also including new steel ends, and as the cars were re-roofed with outside metal roofs in the twenties, the rebuilt cars became virtually indistinguishable from the cars that had been built new with these features.
