Hi Stig,
Intersting information and good to learn new information on the SJ-1 (as I now know
)
Here's another one I suspect may also have been seen before given the origin of the photo. I take it the A3340 on the back of the photo is the aircraft serial. If so here is a photo of Curtiss JN-4D A3340 :

Striking markings. I take it, its still in military service based on the the Curtiss N-8 serial 60 in the background?
Regards,
