According to Mankau/Petrick 110/210/410 - probably the best source to date on Ar 240 development -
0011 would be Ar 240 A-01 (DB 601 E) GL+QA
0010 would be Ar 240 V8 (DB 605A)
0012 would be Ar 240 A-02 (DB 601 E) GL+QB
This does match the data on 1./100 from
www.ww2.dk as V8 is mentioned as Abgang o.F. in August 1943, another DB 605 A prototype (V7) is also listed with 1./100 about that time.
