Well, why have one bedpan when you can have two?
Today’s bedpan is 100 years older (at least) as compared with the one we saw a few days ago. This one dates, we think, from the early years of the nineteenth century.
It is not a mass produced item and we think it would have been made by a fairly local potter. Of course, its function and method of use is identical to the other bedpan.
The UK science museum has a similar looking pan at http://www.sciencemuseum.org.uk/broughttolife/objects/display.aspx?id=5270.
The suggestion is that this pan dates back to the 16th or 17th century. It looks less smoothly made than ours.
