Sony's portable battery-powered turntable from 1983 has become a highly desired and expensive collectors piece. However before I can demonstrate this one, I'll need to get it working.

Ebay (well it doesn't cost anything to look)

UPDATE: After uploading the video, it occurred to to that Sony have in fact revisited their back catalogue recently with the re-launch of the Aibo robotic dog. Hopefully this will continue and we'll get to see some more modern reinterpretations of classic Sony products.
OMISSION: I forgot to mention that I pulled out any remnants of the old felt washer that was protruding from between the cogs before installing my replacement cloth tape.
Also perhaps I should have clarified that the gears unit was welded on at both ends, there were no retaining washers or e-clips that could be removed to disassemble it.
There's also a fan website dedicated to the Sony PS-F5 that has some additional information - https://www.ps-f5.com

The bicolour records used for the demonstrations were:
