Is this a stock 727 Valve Body?

Some time in the early 70's they started cutting numbers in the spacer plate like that. I assume that was to identify what trans type (granny trans, truck trans, taxi trans, etc.) it was for. I have at least 1 valve body with that plate number in the parts stash.

Hope you didn't give much for it cause that input shaft and pump look nasty. No way would I put that in a car expecting it to last. If they put an early input shaft in it they may have also swapped the whole front end to the earlier narrow pump bushing and stator which aren't as strong as newer units
