According to Trevor Legate's most recent book, the MkI was the 260 and the MkII was the 289. The MkIs were all equipped with worm-and-sector steering, while only the first 50 MkIIs were so equipped (after that the MkIIs switched to rack-and-pinion).

The European cars that AC completed were numbered COB (for Britain) and COX (for export to continental Europe), and consisted of both MkIIs and MkIIIs. I think they were all equipped with 289s. AC 289 Sports (MkIII) production began in 1966.

But I wasn't there, so things could've been different in actuality.

Oh, and I think Jeff is right: The MkIV was Autokraft. And for sure anything to do with Lubinsky is questionable, judging from his track record (I wonder if he and Bricklin are ol' chums).
