Decal appliers....no, perhaps Danish or other west European labourers who went (voluntary or forced by their governments like in Denmark) to Germany to work could have been involved, I would not define them as "slave labourers", they were fed & paid a decent salary in most cases. It could of course also have been German citizens, but who knows, could also have been true slave labourers from the East or from the Concentration Camps. Pure speculation.
The angle and placement of the decals on these helmets does however give speculations if a specific template was used for a limited batch period, so keep on posting all your examples including numbers.
