Questions about helmet liners

[Sigurd Helge]

On the real helmets I've studied (only late war helmets) along with plentyful of pictures I've studied (both early and late helmets), the leather sweat lining have seven smaller ventilation holes and four larger ventilation holes (the larger ones are placed in connection where the spanner bolts are attached to the shell).

However, reading Baers book pages 214-221 (the translation of the 1938 LW service regulations), the description ("D") clearly says "four vent holes of 25 mm diameter and seven of 30 mm diameter". Diagram 7 also illustrates this i.e. four smaller (on the top of the liner) and seven larger ventilation "around" the liner.
This contradicts how all liners I've seen actually look like.

Can one find both patterns on real liners?

Holes in liner

Hello

On all the photos I have there are 4 holes in the top (small) and 8 holes around the bottom. Four being larger and the other four small as on the top. 12 holes in total. On a lot or repros and fakes the 8 holes around the bottom are all large. Even the Czechs sometimes have an 8 large, 4 small pattern...the only two real originals I know and have handeled in person have 8 small and 4 large ones...

cheers

You are right Uwe,
I wrote seven were it, of course, should be eight.
But the question still remains, the LW service regulations says something which the genuine specimens I've seen doesn't match.

Can one find genuine helmet liners with 4 small holes "on top" and eight larger holes "around" as prescribed in the FJ para helmet description found in the 1938 LW service regulations?
