Thanks for the links Ed
In particular the third one showing a Ju 52 with a triangular marking on the fuselage. There are other photos from the same unit in the auction from when stationed around Paris. There is also a photo of a Fi 156 with the same marking. We have discussed these markings over at LEMB for some time why I've posted the photos of particular interest in this matter as an addition to the ongoing thread there with credit to you finding them.
