Speedmaster 105.012-66 B2 Crown 32 teeth debate

Hi OF members. I just recently acquired a 105.012-66 HF and it came with a B2 crown, 32 teeth, wide angular feet. I know there are some posts hidden in threads that touched upon this topic regarding the original correct A1 crown (even on a recent 105.012-66 that an established OF member had for sale). Before I try to source an A1 crown (which is becoming more difficult), I wanted to see what some OF members thoughts regarding known 105.012 "actual" Moonwatch examples showing a B2 crown, 32 teeth, and wide angular feet. Is this proof of an "original" crown or maybe NASA had them serviced and replaced?

For example, John Young 105.012-66, Charles Duke 105.012-66, and Harrison Schmitt's 105.012-66 all show a B2 crown with 32 teeth, and wide angular feet.

I also have a 66 CB and it has the same flat foot 32 teeth crown. mine still has the original fat neck pushers and i believe the crown is original as nothing else was replaced on it and it had never seen a service before i acquired it.
