I tried to post the following on the Facebook group but could not make it work: This box car is a 1914 NYC Lines standard of which 7405 were built.It  is similar to the 1912 design of which 16000 were built except it has steel ends. A few of the last 1912 cars might have had steel ends also.As Dennis Storzek pointed out Accurail makes very nice models of these very common cars.The 1907 and earlier cars mentioned on Facebook are much different earlier designs which were the NYCL standards in those years.They were built with steel draft sills and truss rods-an entirely different underframe concept.In the 10's and 20's such cars were rebuilt with composite "repair steel underframes" which had heavy steel center sills, bolsters, and needlebeams.but retained the truss rods.I do not think it was common for NYCL to rebuild cars with truss rods to full steel underframes,although I would be the last to say it never happened. NYC&HR 100145 MAY have been an exception-but I think it was more like a "total rebuild amounting to new construction".Plans for the 1912 cars are in the 1919 and I think 1916 CBDS. Most all NYCL wooden body box cars were modified with strapped or steel ends, revised doors, outside metal roofs,etc.While in general these changes were similar there were many slight detail variations so you need to have pictures of a particular car especially in the later years.(post 1915)
