It seems I managed to find a Holy Grail Austrian item. It is a KAZ M57 Panzerhose. This is the first one I have ever seen except for old photos. And even then I wasn't sure if it was M57 or the transitional 57/59 type.
The only significant difference between M57 and M59 types is snaps used on the leg pockets instead of buttons. Though it is possible the leg pocket shape is "taller" on the M57 than M59. I haven't taken a detailed measurement to see if that's true or not.
The condition isn't great, but I'm happy to have one in any condition
Now the only thing I have to keep looking for is M57 trousers, if they even exist.
