Somebody told me about this question Kenneth!
Thus better late than never.....
.....I've NEVER seen a NO COO 'Tri' DSD. Though the later HK examples (with the flat chest button etc) are the examples usually found on Palitoy 45C and Tri-logo cards!
A NO COO Tri Power Droid does exist BUT is incredibly hard to find; as so few Palitoy 45C cards existed of the figure and there was NO Tri-logo example released.
It can however sometimes be found in German Parker issue baggies (about 1 in 3)!
These are the ONLY examples of the Power Droid figure to be found in Kenner logo bags (rather than the regular black HK text baggies). It's darn tricky to find though.
