Tinashi and Sharlin in-service dates


Having flicked through SFOS, are these correct as intended?

The Tinashi is clearly visible in the 'war footage' shown of the last great war against the Shadows by Delenn, (War without end part 1) putting it well before 2020+.

The Sharlin I imagined was made after the war with the shadows, but it's 1958+?
The in-service dates refer to the current "version". The one you saw in WWE, was a prototype or a really old one, that just happened to have used the same hull shape.
Intriguering... bearing in mind that the other ancients are now around, it might be good to see a 'Shadow War' supplement. You could even stage battles around B4...
