Hot Rods What’s this trunk emblem

Mid ‘50s Trojan.
Sorry, couldn’t resist.

 

I would be guessing a Dodge Lancer of some year, I know they used the knight helmet over the years.

 

58 Dodge Custom Royal grill emblem?

 

Thank you Sir!

 

Answer is always Dodge, and yes appears to be a 1958 Dodge badge, actually would go on the front fenders on Station Wagons, though I usually see them with a Black background, does yours have a part number on the back?
