Hi there,
As the thread title suggests I am trying to identify the symbol featured on one of Mark Donohue's helmets. The symbol/logo is a three-pointed steering wheel with colours and a chequered flag pattern in between the spokes. I have also found a photo of Milt Minter's helmet at Sebring which bears a similar logo. I am sure that the symbol is likely the logo of a racing organisation in the US, however my knowledge of US motor racing is limited. Can anyone help me identify this symbol?
Thanks in advance
