Sure wish I'd done my research first...
Found a copy of this on Ebay and spent $200 for it...
Then I did research and found that WingsAcrossAmerica - a WASP site - has scans of all issues of the Avenger field magazine, as well as something called the Fiffinella Gazette.
Scans available there are for:
First Edition: , February 10, 1943 The Fifinella Gazette
Second Edition, The Fifinella Gazette
Third Edition, April 1, 1943 The Fifinella Gazette
Fourth Edition, April 23, 1943, The Fifinella Gazette
Fifth Edition, May 24, 1943, The Fifinella Gazette
