I guessed the manufacture right

So trying to guess What does this Bellhousing Belong to? Yes a lot of people will most likely guess the manufacture easy enough but, the specific transmission is the real killer that fooled me 😯

I love cleaning out this dealership as there is stuff I would never see otherwise in my lifetime it would seem?

Then other parts auto related are all over this place from more than decades ago. Heck in not to long some of this stuff will be from centuries ago!
