Plate cameras seem to breed if kept together in the dark - I had two Bergheils (one 9x12cm, one 6.5x9cm) and a couple of other "small ones" (AVUS, VAG, KaWee Patent Etui et cetera) together in the cabinet. The big 13x18, 18x24m 24x30 and 30x40cm cameras won't fit inside.

But now there's a tiny little 4.5x6cm plate camera in there too!
