T-85B-1 Transmission Bolt pattern?

Hi,

I have a couple of Borg Warner T-85 transmissions with the R11 overdrive. One of them is a mystery to me and i hope you guys can help me find out what bell housing it matches?
The bolt pattern to the left. What is it? (the one to the right is Ford like the T85C-1A)






What car/engine/bellhousing did this T85B-1 got delivered with?

Studebaker?

Looks like the lower right bolt hole is directly below the upper one on the Studebaker, but on the mystery transmission, it is noticeably to the left.
Note that the lower bolt holes are an inch closer together than the upper ones.
Probably would be better to have this thread in the main HAMB section.
