Technical Vintage Hurst shifter??

I'am stumped, picked up this older Hurst shifter, it's not a comp series. The only number is 032339 stamped on the shifting cage. It's a 3 speed unit. Any ideas what it fits ???

 

Muncie 318 (3 speed) much like this example. Later ones had trans crossmember mount on tail housing. Cut off around 1965 if I remember correctly?
That said, the shifter and mounting hardware will work on later Saginaw 3 speeds (differant shift rods and levers needed).
