There is an Army Map Service set for Central America at 1:250,000 scale, set E503, and we really need an index diagram to show us the boundary footprint of the whole set.  There are other AMS sets for Central America, notably 501, however we don’t know if the extent is the same or different.

We have a made E503 index that covers the Honduras and Guatemalan portions of the set (thanks Chris Thiry!), but we’d like to see the full extent of the set.

If you can share an index, thank you!
