There are two well known photos of the Naglo Quadruplane/D.II available. One is a full frontal view and the other a starboard front 3/4 view, neither of which show the tail structure. I have heard of a mythical WW I Aero issue which not only shows the missing structure, but reportedly also has details of the even-more-elusive Naglo D.I.
I would like to order that issue from WW I Aero, if it really exists. I have emailed them but they cannot help, persumably because of the great volume of back issues/information contained in the archives. Can anyone here help me?
Of course, any other source for the Naglo empennage information would be welcome!
TIA, Rupe
