Yes, definately a fire officer helmet. Some characteristics...the crossed fire axes and fireman helme on the wappen, cruciform spike base. Quite often the fittings are in white metal as in this case and above all...the presence of visor trim on both the front and rear visors. This is always the dead give away. No German leather military helmet has the rear visor trim. I believe that the only reference book available that has pics and descriptions of fire officer helmes is the German reference book devoted solely to Wurrtemberg helmets. B
