The "Fault Group" number indicates the area of the stamp where the variety is located. If the variety overlaps two or more zones, the zone numbers are added together to determine the "Fault Group".
"Click" on any of the (Fault Group) numbers above to quickly see how the system works. The fault must be contained within the coloured area to be a member of that fault group.
If your stamp is already on the site, finding it should be a very easy, two step process.
You will be offered close-up pictures of the various varieties reported in the Fault Group location for the stamp in question. From that group, it should be quite easy to determine if a match to your stamp has been reported.
If you find your stamp on the site, please click the red “Comment/Help” button and report your example.
With two or more reported examples of a fault, it will be considered "constant" and added to Marler and Beyond.
If you do not find your stamp, please consider reporting it to me directly for site consideration.
