Duplex Filofax DVF7/8 - model info

In the product code here, “D” stands for Duplex, “V” indicates vinyl, "F" tells that there are (snap) fasteners, and 7/8 is the ring size in inches. There’s no indication to tell you it’s the wider form of Duplex.

The fact that Duplex binders were made in two different widths is apparently something that Filofax themselves never publicised.
