Remarks

• even after 35 years it still runs perfectly,
  • Only a small foam rubber part, which was totally rotten, had to be replaced by a felt strip.
  • Hinge housings tend to burst due to age related material fatigue. Repair instructions as well as new hinges are available online at widely varying prices.
• A panel weight is recommended, be sure to note the height,
  • so that the weight does not drag on the closed lid, ( Ebay from 25, - Euro )
