G1 variants (obscure and not so obscure)

[heroic_decepticon]

I'm trying to compile a list of USA G1 variants (minus European variants) that were released in appreciable quantities and was hoping for some help.

So far, I consider these variants:

[updated 21 March 2012]

• All pre-rubs from 1984 (due to pretty significant molding differences from some; this also covers metal/ plastic toe cassettes).
• Cliffjumper (yellow)
• Bumblebee (red)
• Ratchet with cross
• Slag (Canadian, red face)
• Snarl (red head, red connectors)
• Jetfire (Matsushiro)
• Blaster - openable battery cover/no battery cover.
• Jazz - Cookie Crisp with no 'Martinni' stickers.
• Astrotrain (with chrome on front light)
• Sandstorm (metal toes)
• Springer (metal chest)
• Scourge (painted hovercraft top/ wings)
• Cyclonus (blue ear)

• Hot Rod - metal/plastic feet
• Kup - metal/plastic wheels
• Rodimus Prime - rubber wheels metal feet/plastic wheels and feet
• Combaticons - metal/plastic chests
• Hot Spot, First Aid, Blades - metal/plastic chests
• Groove - silver chest/gold chest.
• Predacons - metal/plastic parts
• Metroplex - rubber wheels chromed legs/plastic wheels and bare legs
• Ultra Magnus - um... various differences in paint, rubber, metal, plastic and chrome.
• Cassettes with stickered vs tampograph variants (eg: Buzzsaw, Frenzy, Ratbat, Eject, Rewind, Steeljaw(?), Ramhorn(?))
• Autobot Clones (I think plastic chest is the 'rarer' variant in this case?)
• Decepticon Clones (I think plastic chest is the 'rarer' variant in this case?)
• Technobots - no rub-sign indent
• Terrorcons - no rub-sign indent

....

anything else?
