Milk glass 4 leaf bowl

I found this possible milk glass leaf bowl but there are no stamps or inscriptions on the bottom that informs me. Maybe at one time there was a sticker on the bottom. The dimensions are around 6" top diameter x 2 1/2" bottom diameter x 2 1/2" height. I would like to ask for some help in identifying this bowl company and pattern? Thank you . Rob

 

Darn my memory - I used to know this one. I had a set of three: one large and two smaller except mine was clear glass and had ruby stain on the edges.

This probably will not help but here is a listing I found online as follows:

I thought 4 leaf clover when I saw it, the eBoo seller agrees

 

agree the form is not a shamrock but this at chataboutdg looks very similar (unfortunately I don't see measurements): follow the previous and next image links at the bottom or search shamrock:

Sincerely appreciate your efforts and time to find this information for me. Rob
