I believe it's a 1920-ish book case that had been poorly modified.

Thank you for your quick reply, would you mind telling me why you feel it's been modified? Like I said, I'm a furniture dummy! Thank you!

Because some of the drawers look like theya re fronted with fir ply wood, the hardware is inconsistent with the leaded glass of the doors....and I see a 3 panel book case or curio cupboard....if you eliminate the drawers and move the center section down to let it sit on the bracket feet like the side pieces.

I also think it's been uber modified and could have been part of a built-in or larger unit. The bracket feet all strike me as being an after thought and not really well made, they don't even match up where they join. I suspect the center unit was exactly like the two to the side, and the bottom drawer was once on top, as well as a second one. It's been flipped over and the door re-mounted, then raised up to compensate.

I think it was a built-in bathroom storage cabinet. I have seen intact 20's bathrooms with similar designed furnishings. Just never seen one that wasn't painted.
Maybe it was supposed to be installed, but instead got converted into this free-standng unit.

I think it is as-built, but something that has always been a mishmash with strange proportions, along the lines of what Casey is saying.
