Govt contract cap in tip top condition. The "maker" may well not be a maker but a consortium of smaller companys who banded together to get business and compete with the big boys. LL Gen. Mützen may be a generic stamp for that.

hope that helps a little
Yes, Tony is correct. It is for what was called (in German shorthand) a "Lago". The LL is for Landes Lieferant.
