But I suppose, they used the Bf109B from May onwards (?) with Harro Harder becoming the top-scorer of that subtype with 10 kills.

The Berthas arrived in mid-July 1937. I believe Harder made his first kill in a 109 in August '37. His aircraft was 6-36. Earlier kills were in an He 51, from which the unit was transitioning.
