To some people, this has too much of a "Eeeww" factor to consider - if so, read no further...
This is a small PortaPotti, intended for use in camper vans. As far as I'm aware, it was used occasionally for only a few years, at which point it was cleaned and put into storage in a loft - where it stayed for almost 20 years.
It's clean and believed to be in good working order. It's small - just 320mm tall x 400mm deep x 330mm wide approx.
