Internal flush lever for toilet. The lever inside the cistern connecting the flush handle to the flush mechanism. Square section hole at handle end is about 8mm square. About 80mm between centres to other hole [often a range of holes is present].
I need this because, after fixing a new diaphragm washer, I could find my previous lever nowhere - absolutely nowhere. It's possibly somewhere safe like the freezer, but that needs a clairvoyant.
Many thanks
