Vintage Opalescent Milk Glass Candy Dish Pattern Rainfall? Bark?

Manufacturer is unknown. The texture is similar to the "Bark" pattern by Jeanette Glass Co., but the lines are not as large. If I had to name it, I would say it is "rainfall" or just "rain". When I search that for pictures I see some glass very similar but no manufacture listed. The hallmark on the bottom is in the last 2 pics and is sort of an elongated diamond shape, which I cannot find listed anywhere.

Dish measures 5 inches across x 4 inches tall

Dish is in very good condition. There are no cracks or chips. Please see photos.
