When you get it, take a wide piece of masking tape and stick it to the camera back, and then in large red letters write--TURN OFF THE CAMERA! It's very easy to leave the meter on, and find your batteries dead the next day.

Also, hunt around on the net for info on the focusing screen and serial numbers. Before a certain number, it had a screen with a microprism spot, and after that number, it had a screen with a split-image rangefinder spot, and I think a microprism ring. I had the earlier type, but I think the later one would be preferable.
