Saratoga was sisco's ship destroyed by the borg, it had 2 large death ray looking cannons on the side (they had dishes) And the bozeman was from cause and effect, the one that kept colliding with the enterprise's nacelle. I'll find some pix or what not if you need them, wont be that had to dig on these.
Another repluse registrey could be Brattain 21166 from tkyens rift in TNG.
Bozeman is 1941
Saratoga 31911 for sisco's version (or 1937 from "The Voyage home")
(I lvoe this startrek encyclopedia...hehe)
Whoops, forgot the lantree, 1837
