I never found a catalogue that described all these details or assigned number to all these characteristics. The Internet has done great things for philately but not everyone agrees . I can now contact people like me who like to collect and trade covers. I show people what I have and others show me. E-Bay helps with the rest.
Collectors sell small lots of covers.
With a little bit of practice you can find anything you need. Just be careful and patient. I scanned my collection of Canadian Official First Day Covers to help any foreign collectors. Catalogue makers think that they are in the business of selling catalogues. This is wrong.
