Lend lease Spit Mk IXE painting

On a bit of a 1/48 kick of late. Have one of ICMs Spit kits in the pipeline. Question … were the IXes shipped “slick” … no markings? I’ve seen photos of Mk Vs in Iran for hand over with RAF markings painted over and Soviet ones painted on. (Same as US L-L aircraft). Only things I’ve found on the IXes are color plates, kit instructions and a restored one. (which I tend to distrust. ) Also, were any IXes used in areas other than Leningrad area? Only markings I’ve seen are a couple IAPs from that area.

the most interesting options are here. Please note that all options are in the decal with an E-type wing
