What about the solid brass Raliegh (Nottingham) Head Badges? I am fortunate to own a virgin one, never installed on a bike. I was going to use it on a restoration but couldn't bring myself to put in the rivets, so I purchased a used one in good condition off eBay. I don't know if I will ever use the virgin badge, but for now it resides in a jewler's box, wrapped in cotton to preserve it.
I also like the old Falcon Head Badge, mainly because it is colorful.
I do agree that the old head badges were the best. A lot of the manufacturers just stick their logo on the front of the head tube these days. The old head badges were works of art.
