Tudor oysterdate 9050/0 movement questions

Hello! I hope everyone is doing great,

I have one more question concerning the ref.
Mine is a circa 1970s.

It houses a tudor 2784 (that is what is written on the movement) but it has all the specs of a 2783 (non hack and running at 21600 instead of 28800)

Do you guys know any of thes variations of these two movements?

Especially for the vph?

Thanks in advance!

The ETA 2784 was in production from around 1971 to 1978 and came in 17j and 25j and quick set date, power-reserve around 45 hours very fine bullet proof movements.The only difference between them is in the escapement ETA 2783 beats 21600BPH instead of 28800bph in the ETA 2784 and does not use an ETA Chron fine regulator plus the 2873 was in production much earlier..
