hi guys wondering if any of you guys can identify this shower mixer valve from the photos as the manf badge has been taker off it - my daughter has just moved into a house and this is fitted in a shower room and I cant appear to move any of the slider or turn the front button at all so looking for either a replacement or manf name to see if it can be stripped down and repaired -- hope someone can id it for us or give us a clue as how to release the controls -- cheers
