"Black Jack" Dog Dish Hubcaps?

In the late 60's to mid 70's, there were some aftermarket dog dish hubcaps that I believe were called "Black Jacks". The were dog dish style, had a black stripe with no lettering and the center came to a dome shape. They were 10 1/8"-10 1/4" on the mounting surface and were about 2 3/8" tall. They looked similar to the pics of some 1960 Ford dog dish caps I have posted, but are plain without the Ford lettering. Anybody have some or a lead on some. I'm looking for some for my Chevy daily driver.
Thanks.

 

anybody??

 

I see F-O-R-D stamped on them?
