Need Help to Identify Reproducer

[Doc61]

I am hoping someone may be able to identify this reproducer. There are no makers marks or numbers stamped on it. Any help is appreciated. Thank you!

The piercings on the front cover look like the letter Y. I don't know if that is of any help, but I would search brands that began with Y, probably a portable.

That's identical to one that was fitted to a circa-late 1930s Birch portable I used to have.

Here are a couple of other Birch models with the same sound box --
