Firefox, A gentle suggestion, I think we have tried to be helpful to your questions, but your images in multiple threads are out of focus, are cropped too tight to not show the entire stamp or cover, etc. Several replies have tried to provide this advice - the better the visual input, the more accurate the replies can be. No offense is intended, but yes, "Please, work on the quality of your pictures."
When I made my first post here several years ago, I got told "go read your catalog", which I already had and fully understood. It does take a thick skin sometimes as the short replies here often do not convey tone the way a conversation would.
