Hard to believe it's about 50 years old, it's clearly enjoyed a sheltered life or you've been busy with the Pledge It got me curious, so had a poke round tinternet - info a bit thin on the ground, but a couple of things I noted: removable universal headshell (handy), rock solid build (as you would expect), and a tendency for 45rpm to go a bit wayward ( a clean and capacitor change sorts it). 33rpm is unaffected.

I want one, even though I've nowhere to put it

It does seem to be quite rare. I'll bet most are in the US or Japan, as with most premium Japanese vintage hifi it was a time when us Brits were obsessing over our shed-built units.
