TESPONSE FROM MICHAEL KISS BSRP FACEBOOK PAGE
The link provided has all of the copies of the The Philatest, the Journal published by the France & Colonies Philatelic Society. The Journals go back to 1943 and are all downloadable. Perhaps some one in the past 75 years has published a relevant article. Sorry couldn’t be of more assistance. https://www.franceandcolonies.org/philatelist.php
