The plaques states it was uncovered at Alverton, in 1958; Does anyone know just where in Alverton? Just how is it known it was specifically for crushing apples? This area was full of orchards, but not all were apples. How was the cider collected; how were the crushed remains removed and how often; the crushing wheel would have to be very small and have to have a vertical traverse. Was it driven by mule or water? I am puzzled.
