Inner rim: detail to M31 liner of the German helmet. Made of spring aluminum (!!!). Stamp size (for example, 55) in its place.
German helmets were produced in sizes 60, 62, 64, 66, 68, 70. Each helmet size included a liner for two head sizes: 62 = 54, 55; 64 = 56, 57; 66 = 58, 59; 68 = 60, 61. If you can not determine the size of your helmet, please do not buy a random one, but contact us first. We will help you.
If the size is not available, it will not be possible to select and put it in the basket.
