SM mystery cel for everyone to solve !!

Edit : Thanks to a friendly SM collector, the mystery has been solved, so no need to answer this thread, thanks !

Yay my first post ^-^ !

Well, hopefully, SM cel collectors will be reading this ^-^. This is really a mystery case and will interest all of you I'm sure.

I have this great Sailor Venus cel (you can see it in my gallery). Cel, sketch, background, timing sheet, Toei seal, all of it ! I was very eager to get the screenshot... until I actually found it ! The cel is shown in season 3 but the mouth on my cel is off ! This mouth never shows in the sequence I saw ! At first, I thought maybe it was used elsewhere, but it's not a Bank cel... I also thought maybe there was a correction layer to this cel that I don't have. The background is also not matching, but that can happen often.

If anybody can solve this mystery, I will be forever in his/her debt !!
