My name is Eric and I just registered with this group. I wish I could say I owned a Vincent, but I can only dream at the moment. I've come looking for advice. I've recently found a Miller headlamp, and I can't determine which bike it fits. It's unlikely it's for a Vincent, but I'm sure the knowledge base here is second to none. It uses a 5 3/4" lens. It has no provision for an ammeter, only a switch. I am considering a restoration , as it is in overall very good shape, but knowing what it fits would be helpful in determining how much time/money to invest in it. Thanks in advance for your help.
