Two inch bathtub drain source?

Really long story short:

Had my older (1950's) cast iron tub refinished about a year ago, and the contractor that refinished it conveniently did not leave a few parts from the trip-lever style drain in the tub (including the stopper). I rather easily removed the flange piece from the tub, only to realize that it was a two inch drain rather than the standard 1 1/2 inch that would be easy to replace with a pop up or lift-and-turn style drain.


Does anyone make a 2 inch lift-and-turn or pop up style drain?

I have never even seen a 2" waste and overflow drain of any kind. Nor have I ever seen a tub with an opening large enough for a 2" drain.
