The other published location would be FASA's Adventure Class Ships, Vol 2. Those plans are currently held by Seeker.
The linked deckplans above are a variation from the original, but pretty cool regardless.
Another published variation is the Vigilante, from Assignment: Vigilante, a late MT folio adventure set during Hard Times. No longer a liner, but a Q-Ship/Carrier.
I have a WIP re-draw of the T4 version (from T4: Starships) at my site, but it definitely isn't the same hull as the CT version.
