There are no *official* plans for the Corsair, though there are three or four attempts in old Traveller products and a couple on the net.
Judges Guild had one or more, in various products, but I couldn't tell you offhand how close they are...
FASA did one that was double-sized (and supposed to be): the Chameleon, found in one of the Adventure Class Ships folios.
FASA did another one in their magazine High Passage #2. While it's about the right size, it's a box. And an ugly box at that...
DGP made the first attempt at matching the artwork in Traveller's Digest (#16 I think). Blocky, but better than what had come before...
Imperium Games took a stab at a new shape in T4: Starships. In a word (or two): don't bother.
There are quite likely a couple in fanzines that I don't have...
As for the web, there are two attempts at matching the Nishemani artwork (first seen late CT era, and common throughout the MT era artwork).
One of them is mine (found in the shipyard section under campaign ships at
http://members.aol.com/gypsycomet/index.html ) and the other was done by Mark Seemann, and is found at (
http://www.seemann.ms/corsair.htm ).
I'll be the first to admit that mine doesn't have the same level of drafting attention paid to it, but I still like it...
