Brian, Didier Laine was a printer/editor, hence his privileged position to produce these illustrated books. He was also a talented drawer: all drawings in the book are by his own hand. It was difficult to surprise him; once I asked him what the next item on his shopping list was. He answered: "What could I still wish for...". And still, not long before he passed away, he acquired a fantastic helmet, a pristine Pickelhaube for a Mecklemburg general. I don't know how many of you have just even seen one for real, let alone own one... I remember the day when I visited him and he put it in my hands. He was so proud. The crowning of his collector career. I also remember whom he purchased it from...If I may...I would like some additional personal information on Laine if possible. what was his profession, when did he start collecting, was he wealthy in order to assemble his collection and achieve such renowned expertise?? What was his personal background...that apartment was certainly not for the ordinary person.
As Steve pointed out, he was from the same generation as these legendary collectors: Preis, Hartmann (and Steve himself!), and some others in Europe, who probably acquired exceptional helmets at reasonable prices in those days.
(I have added some details in a pm, Brian).
