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

Converter looks like it's just good for a core. All joking aside, it appears to be just a stock converter. The tri-angular decal is a factory decal that would say lo stall if the printing was readable. The converter has looks like it has been apart at one time (crappy welding of the upper and lower bodies) and it's been painted. Factory converters are not painted. The hub also appears in my eye to be worn quite badly. I wouldn't re-use it, except as a core, or a door stop. Stall speed, depending on what it was behind, would be 1800-2100. Nutin' special about it, unless it's had the inside modified.
