Is X326M really a dead end?

[Romantic Technofreak]

Well, I have recognized that my question for Timm's Toys received no answer. But I can't help it, the San Diego Air and Space Museum's Flickr account keeps me busy searching for identifications. The aircraft here is not from Wally Timm's album, but maybe not too far. On Flickr, contributor Batman_60 searched for it in contemporary books, but with no result (the reg shows a Cessna CG-2 glider, Batman considered a General Western P-2-S Meteor). He is afraid X326M is a dead end.
I mean X326M could be a sort of Timm Collegiate. This is more a group of types but a single one. In the picture, I see matches as well as differences to the pictures on aerofiles.com.

What do you say? Thank you for every answer!
