is it the date of manufacture or the shell size?

[kemi]

the Swedish 3 crown stands for made ​​in Sweden for the Swedish Army. nearly all Swedish army things have the crowns printed on the inside. it is like the finnish army they have the SA and the germans have the swastika.

shell size 69 is a small shell size, I prefer a large size helmet, I'll wait until I find a larger size
