Odd big turbo NON Buick

[N2BUICK]

No Buick content I am sure.
I acquired this turbo some years ago,before I knew what are cars could use.
It needs to find a good home,if possible.Looking for some direction on where to "send" it.
It is a Garrett TE06559 ,Red Seal Continential Motors Corp.
Turbine AR is 1.83!
I think it must be an aircraft piece?
More info if anyone needs it. Pictures also.
Thanks
Austin
