Mark,
I quite undrstand your reluctance as it relates to older cameras that are far from any standard. OTOH, I think you will find that a lot (perhaps evenmost of your potential) customers are using modern 4x5, 5x7 and 8x10 cameras that are made in quantity (e.g. Toyo, Canham, Wista, Wisner, Ebony, Horseman, etc.) with readily available dimensional information. My question was aimed at this segment of the market, a segment that is well srved today by both Camera Bellows and Western Bellows, so that those who are intererested could make a quick decision on your product v. that of the competition. OTOH, that may not be relevant if you are more interested in servicing the needs of those using older and more exotic cameras and/or those with special bellows needs. For example, IIRC, a new bellows from MAC for the Toyo field cameras is $125 (don't recall if that is just the bellows or bellows and installation ... but I thought it would be useful if you could give that sort of ballpark info if this is a part of the market that you are intereste in servicing.
