Hello Birgir
I'm not a Ju 87 expert but some info
43 Stukas attacked, both Bs and Rs but I have not info how many were Bs and how many Rs.
identified bombs were 500kg
R could carry a 500 kg bomb
According to an article in Oct 1984 Air International, B-2 could carry a 1000kg bomb as single-seater, ie when WO/AG was left out.
IIRC of the pre-D types only Cs and Rs had capacity to use drop tanks.

HTH
