Hubcaps for a Mercury Custom. What are they from?

What are these hubcaps off of?
Anyone have a set they want to part with?
Thanks

 

You'll need ESP (maybe ESPN?) to see 'em....

 

Added the picture.
Not sure what happened there

 

57 Cadillac....lots of sets in the classifieds

 

'57 Cadillac with a Bullet in the center.

 

Beat me to it!

 

that doesnt happen often

 

Yep, 57 Cadillac with a bullet in the center. Gene Winfield sells proper bullets for them or SoCal has them. I made replacement centers for the ones I had and didn't drill holes in the stock plastic centers as Gene Suggested. There are so many of them on Mercs that some guys think they are Merc hubcaps.
