Sideboard / Buffet?

I bought this piece from an online yard sale page yesterday. My plan was to paint it and resale but I was looking at the hardware and thought maybe I shouldn't until I find out something about it. It's low with short legs, very light in weight, and the hardware has the numbers 3346 on them. It also has 4 doors and the two outer doors have 4 slots in them. The slots look like there was maybe pieces that go there or maybe for records??? I have no clue. Does anyone know what it is and about how old.
