I've been getting nostalgic of late... First good camera I had (I was 14 yrs old) was a Mamiya Sekor 500tl. A few months ago I bought a 1000dtl on ebay with a 55mm 1.4. The viewfinder has a little fungus in it, but the shutter and lens are good and the meter works. The thing is built like a tank. Not bad for $20.
Don -I've been thinking about your comment. At the risk of appearing stupid (as I often do) what do you mean by cool down the colour? A cooler tone of paper? It's a b&w neg and print.
