If I was designing a dream custom film M body, it would be:
M7 with titanium top and base plate, magnesium frame
All exterior parts coated in the most hard wearing black DLC
MP style top plate with no logo, no script
MP style film advance lever
M7 winder
Black calfskin leather
Steel shutter button with polished surround
Framelines for 28, 35, 50 and 75
Titanium shutter
Matching black leather half case
Standard nylon M strap
Signet ring style monogram of my initials engraved on the back of the top plate, but no white fill
Bliss.
