Need help identifying Grandma's Cupboard

I'm curious about the history and value behind my Grandma's cupboard. I think that's what it's called anyway, a cupboard.

All I know is she had it before 1980ish because I remember seeing it at her house in California.
Can you help me identify the maker, year, style, etc.? The only thing I could find on it wasn't helpful = looks like a tag stapled to the back with printed "Belkins Van & Storage Co. Lot. Piece" and a stamped number "62342" under Lot.

I'm more curious about the history than the value, I'll probably end up giving it away one day - been holding onto it for sentimental reasons.
Thank you.
