There is a Calumet wood field XM camera in excellent condition for a good price. I'd like to get it but I had a few questions. The bellows have moderate wear but no pinholes. How hard is it to get ahold of bellows for this camera and install them. Are there any other concerns or things I should keep in mind about this camera? I'll be using it for landscape photography. This will be my first large format camera although I have used a Zone VI before. Thanks, John
