The Phlogiston slowly over time leaked out. I just noticed it , when the supply was run down to about a quarter. Leitz fitted new shutter curtains, and replenished my Phlogiston supply. By the way, you can not interchange the Phlogiston in the screw mount cameras with the one they use in the M cameras. The screw cameras use Phlogiston type XSA and the M models us type XMA. I just thought I warn you about this. It can be critical. Regards, Horst Schmidt
