Dry Flow Tank Cars ?

  Sorry if this has been discussed here prior. I could not find anything in posts. 

While researching, this came up..from page 605 of a 1932 Railway Age is an article on General American Dry-Flo tank cars. Wondering if anyone has a sense of how many of these cars were built. Covered hoppers are still in the future a bit. 

   In the 50s, were these still running? 

 Has anyone ever produced a model (HO) of these? 

                             Thank you in advance.            Jim Dick  - St. Paul
