It seems that the only equipment with a US origin fitted on a German A/C would be the
WendeHorizont Fl.22426 Sperry licence, fitted on Ju 88

So, this Autosyn plate found on a FW190 crash has nothing to do with the FW190
and it is there by pure chance !
All the more as (see "Allied air force" section) that this US equipment would be post 1953, so it really has no connection with a WWII crash.
So, we would really have a FW190 crash site.
