Need Help on Some Shorter and Son Pitchers - Pattern? Age?

Hello everyone - I love these pitchers but have run out of room so I'm planning on putting them up for sale. I'm not familiar with this style of pottery, though, and was hoping someone could give me an idea of a pattern name and/or rough dates of production. Thanks very much!

1930s. The impressed number is the pattern, and they're usually just called matt glazed and impressed. Some did get made after WW2, but yours are earlier.

 

Oh, and fish scale is a keyword.

 

Thank you, Ownedbybear! Just the information I needed. They're a bit older than I thought. And thank you janetpjohn for the link.
