I'm curious too. Condition is very important as many old film cameras require replacement of the seals and mirror pads. This is especially true with O-rings on UW gear. Nikon recommended this every 1-2 years.

Condition of cameras and pictures? Your list indicates a Yashica Mat 134G. The last Yashica MAT TLR manufactured was the 124G according to Camerapedia..."The Yashica Mat-124 G was made from 1970 till 1986 and was the last TLR produced by Yashica"... (copied from their website).
