It works! The Spong patent slicer for marmalade beans and all vegetables! Dear Helen gave it to me. It belonged to her mother, and I believe it to be as good now as the day it was new - probably back in the 1950s. No namby pamby plastic here just iron and a wooden presser to push the orange peel through the funnel at the top of the slicer. It's a brilliant piece of domestic machinery and has knocked hours off the cutting up time I need for marmalade making. The instructions suggest that after use the slicer be washed in hot soapy water and coated in lard - I conceded a little, and used ground nut oil, rather a nice one actually from Waitrose, before packing it back in what is, without question, its original box, until next January!
