We can add that the photo labelled "PZL 46 sum" obviously shows a twin row radial. But the PZL 46 had a Pegasus engine, a single row one... , while that of the PZL 43 was a Gnome-Rhone 14N 01, a double row 14 cylinders.
Additionally there were short struts for the main landing gear legs. Not always can be noticed but the shots taken at the PZL-46 Sum, the Expo exhibition, Paris 1938 show it for the port leg.
