i need some help identifying exactly which super t10 trans i have

[srs244]

i have a super t-10 transmission that i am using for a street rod project and need to know whether it is a 454 "model" or something else. i do know it is a really low geared transmission (6 rings on the input shaft), but haven't figured out how to determine exactly what it is. apparently i need to know this if i want to use something like a hurst shifter as they make different units depending on if it is 454 or a 410 "model" and they apparently do not interchange. can someone help me out with identifying exactly what i have and tell me where to look on the case and what to look for to determine it. the transmission is on the bench so turning it around etc is an easy job i just can't figure out where i need to search and what exactly i'm looking for.

thanks

Do you know who made it and can see the numbers on it or what it came out of ???
