We've had our van for 19 years (1.9 DF, Devon); it came with an Elsan bucket loo (which I never fancied using, so it went straight in the loft).
Recent loft tidy meant the Elsan loo finally got looked at; it had a bag with a few random clips - does anyone recognise them?
Is it to do with the loo?
Or removable table stowage?
Or what?

Thanks in advance for any clues!
