I am now trying to give an overview of all that is known to my knowledge on the never ending story on POTF and MEC Yoda.
First of all:
This is about the No COO Yoda with the small copyright (new COO-Sheet pending)
This COO was released on follwoing cards (thanks to the observations from Stephen and Carlos):
1. ROTJ 65 [?]
2. POTF 92A
3. Meccano 65
Please keep in mind that there is a matching HK COO (related) with exactly the same face and facial details! This one can hardly be determined for sure, so the question is if the Kenner ROTJ 65 really contains the No Coo (IMO)!
I will therefore only keep an eye on the POTF and the Meccano 65 back!
POTF 92A (thanks to Stephen):
Meccano 65 (thanks to Rupert):
The Meccano 65 back with large Trilogo bubble does contain a different Yoda version (different COO):
Here is one further 65 back with correct No Coo Yoda to the right:
So we have two Yodas that share the same No COO and were released on two (at minimum) different cardbacks. We know Meccano never produced figures on their own so the question would be if the very same Asian factory producing both figures
changed the production while delivering the factories that packed them on POTF and Meccano card!
There were observations made by Carlos, Mirco, Lee and myself over the years and I try to give a short breakdown what is assumed to be the difference!
But please have in mind that these differences have occured while producing those figures doesn't mean it is necessarily the same destination they were packed! That means: Both of those variations can occure on both cardbacks! This can't be proven now but maybe in future.
For now, there is indeed two slightly different versions known:
1. Yoda with lighter cloak, lightgreen paint and brownish packman eyes --> assumed to be POTF only
2. Yoda with normal (darker) cloak, normal green (darker) paint and blackish "full" eyes --> assumed to be Meccano only
The "full balck" eyes are IMO just oversprayed. The slit (pacman shaped eyes) can be present more or less on the black eyed ones.
The brownish eyes can vary. They are not really brown but are also not solid balck. The amount of color used while spraying those will result in lighter or darker bronish ones. The always have very clear "pacman" shape and form.What also can be seen is: The POTF seem to be sprayed with a lighter green on hands and feet:Also can be seen on Mirco's (Mike_Skywalker) example:Note that my POTF snake is discolored!
The question about the accessories is difficult, but from the MOCs we have seen above at least the colors on snake and cane are 100% proven.
IMO these both come with "noncircled" accessories. Stephen always called the ones with EPM "European Yodas" because he hasn't seen circled accessories on Kenner cards. The related HK Coo to this POTF/MEC Yoda appeared on Kenner cards and therefore has "uncircled" accessories. Regarding that the steelmolds normally go together (accessories and figure) the No Coo therefore should come with "uncircled" accessories in both cases (like my examples).
Of course many of those got mixed up in the last 30 years....so not every Yoda found in the wild comes with its original accessories.
This is a first attemp to give some answers and I hope you like it!
