In the Apr 23, 2019 PLAN 70th anniversary parade, the 093 and 093A show up together. Photo of 093A first appeared on the web in 2012, but by 2019, the 093 has clearly not been modified when we've already seen three variants of 093B. There're other recent photos of 093 showing their sail remain unchanged.

The 2016 magazine also listed it as a separate class.
