Electric piano (Tavistock PL19)

Yamaha DGX-200 Portable Grand.
Sold on eBay more than two years ago to buyer in Dagenham who never arranged to collect it. Already packed in original boxes, one for the keyboard and one for the stand. Bought in Japan but used in England and of course has UK adaptor. Instructions in Japanese but pretty self-explanatory and I imagine English instructions can be found online. Please note I am not willing to unpack to demonstrate it.
