Steve, those makers that made only one size tend to be rarer, heres a quick list of known mm, other marks exist, but there meaning/makers are lost to time :-
Maker name/City. Maker code. Sizes produced.

F.C. Bellinger, Fulda B.F. 62,64
J. & H. Kerkmann, Ahlen/Westf K. 64
Gebrueder Gnuechtel A.G., Lauter i./Sa. G. 62

The most common M16/17/18 helmets tend to be the 'E.T.' mm helmets as they made all sizes, plus the only model of the super rare M18 cut-away model.

What is the marking with a bear and under that 64.

cricketchris1944, I didnt include Austro-Hungarian made helmets in the list above, but the 'Bear' logo is 'Berndorfer Metal Warenfabrik A Krupp A.G.' of Berndorf, Austria. They made the M18 Hungarian, M16 Berndorfer and variants, in size 64/66.

you are the man.

I have been looking at other Bell helmets for a few months now .
They all kind of look different from each other.
Probably cheap labor or manufacturing.
But this is the worst one I have seen.
Could this one be a reject?
