I have spent the last 3-4 days setting up a stock of Peru. Much of it is easy to sort but the definitive sets were made by different printers and these are listed separately. I have good quantities of many of these issues. This stock covers stamps from the early issues (just a few) through to the 1990s (where it peters out).
I now have five Latin American countries where I need to set up the stock. Once that is done, I have a number of collections and stockbooks currently housing more material. It will be nice when this is all done!
