What head badge ?

[vince72]

Is there a way to know what head badge is original to a bike? I picked up a 39 dx and am wondering if there is a way to know what head badge it came with?

I just got a 1941 DX with an Excelsior badge. I removed the badge to check the non exposed paint and it matched the outline of the badge. I’ve been checking the CABE and other sources for 1941’s that have Excelsiors for a badge. I have come across other badges that could be used on the DX.(Same outline)

no way of knowing unless there's a downtube decal on board...a tank with a badge name....
or a peculiar outline for a recognizable 'odd' badge
