Reader Steve Morton has come through again. After I posted the scanned Customer Record page, he has given us the gift of Word and PDF versions of this useful page in A4 and A5 that all of us can download and print.
The Word and PDF documents are available for free at: http://groups.yahoo.com/group/filofax/files/. (You will have to create a Yahoo account if you don't already have one, and join the Yahoo Filofax group, which is, in my experience, a well-managed and spam-free group.)
You can also find them on D*I*Y Planner at: http://diyplanner.com/node/6518.
