F1 drivers helmet, design, year, brand...

[f1 canada]

Hi! All...I am new here but think you guys are Pro's! I 've been collecting some old Helmets recently that I would like to turn into F1 driver replicas...They are mostly from the middle 70's, mostly Bell star...
Does anyone know a good book or internet site were they should good color photos of older drivers helmet?
Also, would anyone know a reference site that would list the helmet model that such and such a driver was using?
Example: Merzario, Bell star II, 1975...(maybe not accurate!)

Would really appreciate because I want to paint a few one and have them look as original as possible...

Thanks, F1 Canada

I had a link to a Swedish site (I think) from a couple of years back that detailed a lot of sportscar and single seater drivers helmet liveries. The guy who runs it was on a sportscar forum thread about something or other, i'll see if i've still got it in my subscriptions.

Unfortunately i lost the link and couldn't find it again but someone else is bound to know who runs it.
