I figure it's a long shot, but I've had stranger 
things happen. . . I just found that the two 
layers of one of my Mosquiton OVA cels come from 
different parts of the given sequence. Below, 
I've put both a scan of the cel (as I have it), 
and screen captures of the exact frames where the 
two different layers appear.

If anyone out there has either the Yuki layer 
(that would go with my "dirty old man" layer) or 
the floating shorts layer (that would go with my 
Yuki layer), please let me know! I'd love to work 
something out with you. ^_^

Also, if anyone else has cels with missing or 
mismatched layers that you'd love to find, post 
them in this thread and we can see if any of us 
can help each other. ^_^

Many Sharp Smiles,
