Aerofiles mentions a H-634 Twin Stallion 1968 with two 317hp Allison 250B mounted on a stub wing in the nose. One was built with registration N11038. A version with two 620hp PT6-A was planned. May be that was your H-1201T.

Where did you find your reference to H-1210T?

H-1201 Twin Stallion (no 'T' in the designation) was a 1966
proposal designed to carry 13 passengers and two crew
but was never built.
