Thanks for someone pointing out the missing "a's" in tray (too hurried or too old or both). I've corrected the statement below.

I am unaware of any list of chain line measurements from that work, but perhaps someone else has that information. From Bland's _A Guide to Early Printed Books and Manuscripts_:

    ...it is important to distinguish between marks that derive from
    different states of the same tray, and those that derive from
    different trays. This is where the measurement of chainlines
    proves to be crucial, for marks that derive from different states
    of the same tray will always have exactly the same distance
    between their chainlines, even though there has been a shift in
    part of the image, whereas marks that derive from different trays
    will have different distances between the chainlines.

There is added discussion concerning the complexity of watermark image analysis in his chapter "Paper and Related Materials."

Dear Maphisters,

just purchased David Woodward's 'Catalogue of Watermarks in Printed Italian Maps 1540-1600', 1996, to get more details while cataloguing some maps.

Since the mark itself changes it shape very much during the usage of the paper mould, it would be very useful to have the distance between the chain lines, which should be almost constant over the usage time. Especially, if only a part of the watermark is present on a sheet. Unfortunately, Woodward does not mention this distances.

Does anybody knows if there is a list for chain line distances, matching with Woodward's catalogue?

Thanks,
Rainer
