General Electric Stereo Console 1960's

Hello! I recently picked up this General Electric stereo and need some help identifying and dating it. From my research I believe it is from the 1960's. I've seen very similar models and they date between 1966-1969 but I'm not sure about this one. If anyone knows anything about this piece I would love to learn! Thanks

What I know:
-William Tell Woodcrafters made
-not sure about the serial number; two numbers on the back:
D136131 and DW17

Thanks
