What kind of valve body and TC is this?

I pulled the pan off the replacement 727 my buddy gave me. This was the original 76 trans with the 440. He said it was rebuilt and it looks clean with very little stuff in the pan. He said it had some sorts of MVB but there wasn’t any paperwork from the original owner. Anyone recognize this? The TQ has an unreadable tag on it. Any help with what I have? Only numbers I can find on VB is 35454 E. Thanks Craig
