If the Flying Machines Press French book is to be believed, then MoS Type AI's were formed into three Escadrille's: 156, 158 and 161. I have not only the FMP book, but also the Mini-Datafile, Windsock Vol 8 No 3, and Over the Front, Vol 9 No 1 (which contains a short history of Esc.156). Are there any other photo's of MoS Type AI's besides these sources? Specifically, are there any photo's of MSP 161 machines? TIA!
