Replacement complete old style flush plate. Plate size 155 x 85mm, diameter across the chrome collars is 47mm. Oli have modified the bellows canisters on the back of the buttons. The buttons we send you, though visually different, will work, but only if you have the new style flush valve and control block (see photo 3). If you have the old style versions, you'll also need to buy TS324 & TS333 in order for the modified buttons to work. If in doubt, please email some photos and we will advise.
