Vultee would mean a Su-2:

When you look at claims: All these wrong names were only used in 1941, when Germans didn't know what types were used by the VVS. Similar to Russians claiming Heinkel-100 and so on.
PS: I have a german identification booklet "for 1943" with 3D-views for most nations. It already includes that "the IL2 may have a rear gunner", but also the still the R-10 as Reccon...
