NKL-16M Hydrosan, Lake Ladoga, 1941
The model shows one of the dozen or so NKL-16Ms with Red Cross markings, ostensibly for humanitarian missions (serious casualties out, medical supplies and personnel in). However the beseigeing Germans suspected that these vehicles were actually being used as couriers for intelligence, orders, and VIPs. The Soviets of course, denied this emphatically.
Local commanders requested that Berlin make 'enquiries' through Red Cross channels to ascertain exactly what was going on. However the OKH decided against this, for fear of turning the spotlight on their own 'indiscretions', regarding the Red Cross . . . it is likely that the truth will never now see the light of day . . .
cheers,
