Very sad news indeed...
Although I took notice of Propliner magazine only in the early 90's I was able to get every single copy from the Mr. Steven Pearcy era till issue 137.
It was the kind of magazine that had thorough and well researched articles (rare in the aviation editorial world nowadays) combined with excellent pictorial material. Its content was kind of exclusive and rarely appeared outside it - event after the Internet era.
After the demise of World Airline Fleets News in 2011 and the recent sale of Airways magazine to a new Editor (who I my opinion changed the magazine to worst), true aviation magazines for the hard core aviation enthusiast are slowing disappearing.
I surely will miss Propliner magazine....
