It's one of a growing number of reconditioned players on eBay, with a good number of people out there taking old Dansettes and returning them to original and working condition. This one is clad in its original turquoise cladding, fitted with a BSR UA16 Monarch autochanger turntable and with two brass capped controls mounted on the front, one a combined on/off volume, the other a tone.
The seller confirms it has been stripped and cleaned, the single valve amplifier serviced and any worn components replaced. It doesn't have the legs, but it is compatible with legs if you buy some on eBay (there are plenty out there).
If you fancy it, the bidding right now is at £4.99.
