Looking for some input regarding an m31 liner

[Byzantium]

Hello everyone,

I'm new here as a user but not as a lurker, have been visiting these forums for quite a while to look up information or simply to just keep up with updates etc.
Mainly interested in (German) steel helmets, this is also my 'area of expertise' although i'm still learning every day. I was hoping to get some input here regarding a Quist i have.
In particular the leather liner. I'll try and post some clear pictures when i get to it. Anyways, thanks for having me here and hope we can all share knowledge together.

Cheers and have a good day,

Byzantium
