NASA and Hasseblad book

I am preparing a book about the collaboration between NASA and Hasselblad from 1962 till the end of the Apollo program in 1972.

I am looking for any kind of data about 500C, SWC and 500 EL cameras used by NASA: how they were prepared, technically modified and enhanced, some photographs, Hasselblad serial numbers and NASA numbers ...

I would also like to make an inventory of Hasselblad cameras in museums and private collections around the world.

All photographs published in my book will show "Collection of" with your name  or simply "Private collection" as per your instructions.

Thanks in advance,

Your host,
Alain.
