Canadian bank of Commerce bowl identification
I am reaching out to the community for help in identifying this strange bowl I have. It says "The Canadian Bank of Commerce" in a circle logo that has what appears to be a medical symbol of sorts. It also has a dual screen type attachement. It appears to be silver, turning black, but the inside is turning green (indicating copper, from my understanding).
What I am interested is any information about exactly what kind of bowl this is, what it was for, etc.
Any help would be appreciated.
Here is a link to the pictures I have of it:
