Colt had its version of the old S&W "service stocks". My 1951 Cobra has those and a T-grip works fine. Since your MBH's current grips (which look right for that era) already fill the space that a T-Grip would occupy, I don't see one working for you.

(OK purists, I think I used the right nomenclature for the wooden parts of S&Ws and Colts. Just don't ask me about yokes and cranes)
