The very first of the Optimus Prime reissues was the 2001 Takara "Convoy" (japan's name for Prime)

This is a dead on reissue of the 1985 version.
After the popularity of 2001 version, Takara made a 2002 version called "New Year's Convoy"

This version is "anime accurate" matching the cartoon with blue eyes and blue windows. There are extras in the box including a matrix, action master convoy, and a mouse pad.
In 2002, Hasbro brought reissued Transformers to the US. Toys R Us saw this version:

due to safty regulations, smoke stacks needed to be cut down and missile length increased. Castrated Optimus Prime is G1 accurate otherwise.
2003 brought the Transformers Collection (aka TFC) #00 Convoy.

Seen as the best of the Convoy reissues, this one has an energon axe and is in a nice box display.
