Caption: Asiatic Fleet camoflage on a PatWing 10 PBY-4. The lack of waist blisters and the older style rudder identify this as a "Dash 4" but the locally prepared multitone scheme, thought to be shades of blue and gray, conceals nearly all the former markings.

PatWing 10 later flew PBY-5s, which have a newer-style (squared-off) rudder and waist blisters; I don't know if they ever flew PBY-1s, -2s, or -3s which looked similar to the PBY-4.
