Cool record changer.  For those who haven't seen one, you could stack LPs on the tall spindle and the turntable will drop the next LP one at a time after the first one ends.  This is why some double albums are numbered 1 & 4 on the first LP and sides 2 & 3 on the 2nd LP.  After listening to sides 1 & 2 you just flip the two played LPs and replace on the spindle and hit "Start".
Wonder what  Louis had on the reel to reels.
