After tough bargaining

I could get this Erma conversion in the large wooden box from a friend; condition like new - all matching - with regimental marking.
Unbelievable that at that time the armourer thought that it is necessary to mark the cleaning brush, too
But for me the main important thing, never seen before, is the target test paper coming with the box, in a little envelope; very thin paper - thank God that it survived in the box more then 70 years....
