Feroze,
F magnifier was introduced for SF1/SFX cameras,
FB magnifier was introduced afterwards
I believe them to be identical.
The magnifiers that fit on the K-1000 are the older type.
They work with KM, KX, K2, and the old Spotmatics.
They are abundant on ebay.
I've used the FB magnifier and refconverter A or M on
ME, ME Super, Super Program/Super A, and PZ-1/PZ-1p.
The eyepieces are all identical mounts and they work fine.
The magnifier that fits the K-1000 doesn't work for the later cameras.
The dimensions of the eyepiece are different, slightly smaller I think.
Folks have talked about grinding a bit off of the mount on the old ones.
Other comments are added below...
Regards, Bob S.

F came with the 'F' series cameras & lenses (SF1/SFX)

I don't know about the MZS, the rails of the KM, KX, K2 &
K-1000 are of a different dimension than the PZ-1p or ME Super.

Magnifier is a straignt thru thing. Snap it down & get a 2X
view
of the center of the viewfinder. Snap it up and you'll look
thru the
original finder window, not thru it. If it gets in the way,
dismount it.
