One of the things about my new Michael Ritchie is that I don't need/can't use certain things. These are in great condition—I've checked the prices then knocked a bit off.
I have an Abel armrest, not needed for comfort with the oil-rubbed finish, quite new and in perfect condition (I can't imagine how you would damage one of those without a fair effort anyway): £25 + postage
1 x Johannes Tappert Ergoplay, not really usable with the oil-rubbed finish and in perfect condition: £15 + postage
1 x Ergoplay standard model, also in great condition: £10 + postage
Hope they're of use. It would be easier if they're sold in UK...
