I have what looks like a Herbert Jhonson? vintage crash helmet.in what looks like British raceing green colour.
What i need to know is how can you tell what make it is and what year etc, there is just a number 174, written on the inside and a size label.
a few pictures also added, if it is a real H,J. then i would like to find out any history about these helmets,
how many produced and who used to wear them etc.
Any help with the Helmet would be much appreciaited.as i seem to find very little info about them on the web.
Many thanks Rich.
