The helmet is very plain, with an integral crest knob.
The front edge of the helmet bowl has been 'knocked back' to thicken it,
The neck guard is small and is almost horizontal.
There is a single hole in the centre of the neck guard, where there would have been a fitment for securing the tie laces.
There are the usual pair of holes in either side of the helmet bowl for securing the rivets that attached the cheek guard hinge plates.
It should be noted that both Klumbach and Paddock regard this helmet as belonging to the "Hagenau" group. However, it seems to belong more with the Montefortino "C" types as the crest knob is an integral feature and the shape of the helmet bowl is more conical than it is hemispherical. Also, there is no trace of a brow guard ever having been fitted.
