It looks like I answered my own question... and added a few more! This is a photo I found on a google search - it comes from a publication, see the translucent text upper left! So for research purposes again - sorry if I tread on toes. A very defunct WW1 site says this may just be a Jasta 15??? aircraft visiting Jasta 5 but gives no proof... I think the caption of this photo is correct though...

All The Best,
Marc
