Hi Larry,
I fully agree that we have not yet the complete overview of which Ju52 crashed where on May 10. The list of Mr Brongers you refer to is an impressive overview and starting point, but basically a compilation of all claims and reports, and definitely not all correct. (And not reading dutch doesn't help much either

). Peter Cornwell made a big step, but also his list still contains gaps and as I see it some errors; we had a good discussion on some of the entries (unfortunately under time pressure of the manuscript). So continued research remains necessary.
Regarding the unit codes of the KGzbV units that were part of the transport fleet:
KGzbV1 1Z+
Stab/KGzbV2 G6+xA
- KGrzbV9 9P+
- KGrzbV11 G6+xD, T,U,V,W (this was the former III./KGzbV2)
- KGrzbV12 G6+xB, H,K,L,M (the former I./KGzbV2)
- I./KGzbV172 N3+
It is indeed interesting that the majority of pictures of crashed Ju52's are of KGzbV1 aircraft, followed by KGrzbV9. Pictures of aircraft coded G6+ and especially N3+ are a clear minority. Would be nice if you had some of those.
Regards, Pieter
