I answered 4 but I think it's between 7 and 10.
Polaroid Land 250: Fuji FP-3000B
Leica M2: Kodak Ultramax 400
Pentax Super Program: Ektachrome 100VS
Pentax MX: Kodak Ultramax 400
Yashica 635: Kodak New Porta 400 120
Kodak Medalist: Kodak Portra 160 NC 120 (on 620 spools, natch)
Kodak Folding Autographic Brownie No. 2: Fuji 160 NPS
I think, but am not sure, that I have Kodak Ultramax 400 110 loaded in my pentax Auto 110.
Also, I have Fuji Provia 100f and Iflord FP4 in my film holders for my Super Graphic and Toyo 45F large format cameras, but since the olders aren't actually in the cameras the camera isn't loaded. So take your pic on those.
