MK, MKF, KMF, MKS factories? Are these all different?

[r6538]

Been catching up on the PP rep scene and on the first two pages of the forum I currently see MK, MKF, KMF, and MKS factories.

KMF Aquanaut: https://forum.replica-watch.info/fo...t-showdown-v6f-vs-zf-vs-kmf-exhaustive-review
MK Nautilus: https://forum.replica-watch.info/forum/patek-philippe/7114955-nautilus-help-pf-vs-mk-v5
MKF Nautilus (sticky): https://forum.replica-watch.info/forum/patek-philippe/324248-nautilus-comparison-pf-vs-mkf
MKS Nautilus: https://forum.replica-watch.info/forum/patek-philippe/7121796-new-mks-vs-pf-5711-blue-dial-video

It's a little hard to know if these are typos or all are truly different...

I am trying to find a KMF aquanaut to purchase but can't seem to find it on Puretime or Intime. Makes me wonder if I should be searching for one of the other ones???

MK=MKF=MKS. They are just name variations.
KMF is completely different.
Not all dealers offer KMF.
