Wow! a Umm al Quwain appreciator!

After 10 years of having a complete messed album of these labels,
it finally dawned on me, to establish a Michel Code.
So I now code each stamp with a Michel Page number then the Catalogue number.
Everything just fell into place, and I can find the sets without thumbing through endless catalogue pages.
Dante's Inferno remains the challenge, yet to see a full collection...........
