Harker Hotoven Chinaware custard cup bowl Mallow vintage 1930s 1940s floral

I believe this vintage piece of Harker Pottery is from the 1930s or 1940s. The pattern is Mallow and this looks like a custard cup. Pretty floral design on the front and marked on the bottom. Some minor wear but no chips or cracks. Measures 2 5/8" tall and 3 1/2" across the top. Smoke- and pet-free home.
