Thanks, everyone, for the fascinating stories!
I had no idea biplanes were so common back then, and also even not long ago. I only flew i that one once. Wish I could remember a lot of details about that flight, but all that is lost in the mists of time (can't remember it). Wish my one and only photo of that Dragon Rapide showed more details, including the whole tail number, but there are people in the way.
