1. Nikon F2AS, Nikon F2A and a pair of Nikon F3HPs for 35mm shooting. A 500C/M with a 50, 80 and 150 for medium format work.
2. Kodachrome 25 and 64for all my colour work, Kodak Tri-x, Ilford PanF and HP5 for black and white.
3. Kodak paper (Polycontrast?)
4. An Omega D2.
So...beyond updating my 35mm bodies, adding in a Leica rangefinder system, and accumulating a lot more lenses (in both 35mm format and 120), I have made only minor changes (Ilford for all my paper and the lion's share of film and chemistry, and Ektachrome for almost all my colour work) to my photography (if the tragic loss of Kodachrome can be deemed minor).
