Starting around 1959, not counting quite a few long-term borrowed cameras over the years:
Canter Beauty
FR Reporter (2-1/4 x 3-1/4)
Kodak Retina 1
Miniature Speed Graphic
Nikkormat FS
Leica iii-f
Canon ii-f
Leica M3
Leica M3
Leica iii-a
Olympus OM1
Olympus OM2
Leica M4-2
Leica M2
Nikon D300
Nikon FM
Nikon FA
Nikon FG, x6
All of the Leicas are gone, except for the iii-a.
That's blowing off some side-trips in to other formats. (Hasselblad, currently).
You can see I'm sort of wandering backwards now, my main machines being FGs with various films in them, spotted around in various places, like work, home, etc. The FG is functionally an M6-TTL, and that's good enough for me.
