Skeps were a specific size. Look up the word in the Oxford English Dictionary and you will find it was used as a unit of measure. A skep of grain, a skep of coal. It was also an office trash can, and about that same size.
If you will find and look at Dideroit's Encyclopedia of 1660 you will find illustrated there special tools for cutting combs out of skeps. Just FYI. Not to tell you how to use skeps.
I'm out. It was both the non-removable comb and the hand coating with fresh cow dung.
