Page 15 of RPC Vol II, shows one of the Navy Gas & Supply cars. The caption
indicated that CTTX 8000-8508 were built in Jan 1931, and 8509-8510 were
built in May 1931. Since the photo is a builder photo I can't help with
reweigh abbreviations. Tank cars had to be reweighed every 30 months, I
think, I know reweigh time frames were covered on this list and a search of
the archives should turn up the definitive answer.
