I had this bearing commissioned for my 401 twin arm plinth, It was the one from the top of the specs as it was eye wateringly expensive (about £2800 as I remember) it is beautifully built with Lignum Vitae wood used so semi self lubricating. Its almost to pretty to hide under a platter and needs to be seen to appreciate the looks I think.
I would like to get as close to £1000 as possible but open to sensible offers.
