That looks like a rare one! I've never seen it before.
It appears to be intended for use as a chairside or end table when not being used to play records.
RCA did make some upscale 45 units, though most were intended just to be plug-in attachments.
The one below is styled to look like a small Colonial chest, like a large tea caddy; it was the attachment intended to be used with the Berkshire Breakfront entertainment center, which came originally with a 78 changer:
I absolutely adored these RCA 45-rpm record changers when I was young. Mine looked more like this one: No cabinet or cover, but it had a built-in amplifier/speaker.
Spent countless hours stacking singles on that little thing and watching it go!
