Model 18 Type German Fire/Police Helmet-This has a heavy steel construction, and a droop tail visor. The black paint is 80% intact. It does have a single screened ventilation hole on each side. At one time, this had metal shields but they have been removed and there are two holes where they were attached. The interior of this size 55 example is in excellent shape, and still has the leather neck flap. The black leather chin strap with the snap ring attachment is intact and in very nice condition. Interesting piece!
