Trying to find out what year this china cabinet was created and who was the manufacturer

Hello,

This china cabinet was owned by my mother. We live in Rhode Island. This item is older than me, and I am almost 60 years old. My older siblings have known this cabinet for many years prior to me. My oldest sibling was born 1950.

Any idea who manufactured this? What year do you think it was manufactured? There are no markings except for a number "10" on the back left hand side. There are holes to attached to a wall, I am assuming. I'd appreciate any information anyone could give me.

Thank you!

Mary
