Does anyone know a dealer with lots of good quality classic Panama stamps? I'm looking at expanding a US possessions collection into the Spanish era too, so looking for Cuba, Philippines, and Puerto Rico too.
Latin American Philatelics is also a very active buyer on Delcampe, for their own online store (and I'd reckon to fill want lists too). I know as they have bought quite a number of items from me over the last year for some of the other LA countries.
So you may want to look at sellers with strength in those countries on Delcampe as well.
