Is this American Brilliant?

I Found this what I assume to be a relish dish at an antique area of a furniture store in Brenham, Tx. It's 11 1/4" l x 4 3/4" w and as far as I can tell is in perfect shape. I can neither see or feel any cracks or chips. I've looked with my lighted magnifying glass, to see if there is a makers mark anywhere on it but haven't been able to see any. The photos show the different areas of the dish and also the bottom.

 

Certainly looks like ABP.

You could use "celery dish" for a search term.

If marked it should be in the center of the bowl. Sometimes if the glass is damp, not wet, the mark will show better.
Not everything was marked. Many had paper labels.

 

Sometimes a maker's mark is etched very lightly and small, dead center on the top surface. Letting glare play over that area sometimes helps in seeing it.

 

Thank you, I'll try getting it a little damp or with my phones magnifier app. Tried, couldn't find one.

 

Worth the effort anyhow. It's very attractive.

 

Thanks, I have lots of other pieces that may or may not be American Brilliant that I may post. I'll sit down and see if I can find any marks on these using my magnifier app now that I have it.
