I'm considering making an offer on an 8X10 B&J camera that has an extension rail. It has been sitting in a box for 9 years and the owner can only say the bellows are supple and to the best of his knowledge light tight, or they were 9 years ago when he last used it.

I would like to offer a bid assuming the bellows needs replacement. Does anybody have an idea what that cost might be?

I looked at a couple of sites that replace bellows but before they can offer a price they need to know precise dimensions and I can't supply that.
