I'm selling it because I bought a Canham 6x17 back to use on my new 5x7 camera. It eliminates the lens restrictions and is a bit less bulky to carry since it's just one piece. Of course the 5x7 is more bulky, so I thought about keeping this one too.
I'm not sure the price is high. New ones are about $569 on ebay. I bought this used for $500 a few years ago. But if it doesn't sell, then I guess the price is too high
