Oh, the mysteries that land on my desk.
Just took these shots on my phone, as I haven’t accepted it into the collection still trying to figure out exactly what it is and how it works. The label says one thing (Magic Egg Brush), but the spring at the top makes me think there is more to this gadget.
Off to search through more catalogues…
Nevermind, mystery solved. Thank goodness for legible labels, I was able to read the patent number and search from there. Huzzah!
