Some info needed by the Brain Trust here. A question about the Aurora.....

Knight series. I always labored under the impression that Aurora issued only five Knight kits, which were the Red, Blue, Gold (on horseback), Silver and Black Knights. There was even to be a Green Knight (prototype) that was to be issued but never was. Now surfing the web, I have been coming across pictures and references to the fact that there were at least two other 1/8th Knight kits produced by Aurora, but for the life of me I can't ever recall seeing these things in the flesh. Both seem to be Crusader Knights of the 1100s. Both have shields, spears and conical helmets. One guys shield has a rampant lion on it, the other looks like a round shield. Am I missing something, or were these kits issued by another model company and people just lump them in with Aurora? Were these perhaps part of some sort of "Camelot" thing? Anyone have the definitive Aurora book they could shed some light on? Thanks for any help. Scott.
