Aviation World - Winter 2019 Feedback

I enjoyed browsing this edition, some interesting articles in there!

One comment, regarding the entry for Stinson SL-AAN in the Saarland register. Serial 41-5143 is not valid, it was from a cancelled batch of Douglas O-53.  Could it have been 41-143, as I note that Baugher lists the next aircraft 41-144 as c/n 7250?
