Help me find these mystery wheel covers please

I am looking for a set of these, they are pointy, not rounded, and are 15". Late 50's - early 60's vintage. Pic taken in about '60-61.

I have heard Plymouth, but as far as I know, Plymouth were 14" not 15".
Also heard they may have been aftermarket back in the day.

Anybody???

 

They're aftermarket 57 Plymouth style wheel covers.Don't know who made them but they show up at swap meets occasionally.

 

Humm, they kinda look like these on my dad's old ford in '65. They were 15" also...

 

Saw a set of 14" out at Carlisle.....I have 15" on my 55 chevy......I found them one at a time at swap meets......good luck hunting for them.....stan

 

I'm hoping someone here happens to know of a set. I found a set of Duster wheel covers that were pointy , but were brushed and not chromed. I suppose I could have them chromed, but they wouldnt be authentic.
