Re: Excuse me ..
Wrong.
For some unknown reason the bf109 and if I remember rightly the bf110 were both referred to in that way officially until the end of the war. The Me210/410 was designated after Dr Willi (and he probably wished they weren't) but it wasn't backdated for some reason.
The only bf109 you'll find with an Me109 build plate would be some few that were repaired/refurbished on the eastern front. In Estonia I think.
If any survive they'd be rarer than dodo's teeth.
