Hello,  I have a master database which contains several thousand
listing for Ampico, Welte and Duo-Art rolls.  This can be useful for
limiting typing when making a personal database of ones own rolls.
I also have a database of Welte rolls which was produced from scanning
and OCR converting the images that Terry Smythe made from the Smith
Howe Welte book.

These files are available to anyone who can use them.  If they and
other databases are shared, it can considerably reduce the effort
of making personal databases.  I am not familiar with John Miller's
database software but it is likely that information from other sources
can be converted to a suitable format to be used by it.  I almost
remember checking it out for a friend and think I remember that it
was a template for something like Microsoft Access.

Best regards,
Spencer Chase
