What are these stamps in my feldbluse?

[K Bandow]

I was wondering if anyone can tell me what these stamps are in my M36? I can make out "Gebr." That is about it.
Any help Appreciated!

Here is where they are on the interior. There are the same stamps in the same spot on the other side.

Might they be unit stamps? I can make out a number 34 in there.

Hello Karl,
I think that Gebr is abbreviation for 'brother' so it may be a tailors stamp (as in 'Moss Bros') - that's only a guess! Maybe a native German speaker will help

Hello,
the stamp, may be is the stamp of start or finish of the original roll of cloth that the maker used to made the tunic liner. Is not very rare to see this type of stamp in the jackets but is more common to find it on fieldgrey or black wool cloth.
