Analysing - 18th century muffs

I have given making another 18th century accessoire some thought. A muff.
A while ago I have seen this tutorial by Kathrine http://koshka-the-cat.blogspot.de/2013/01/an-18th-century-muff-cover-tutorial.html and thought it was a rather simple task. Unfortunately she doesn't give any reference as to the suitable decade. To cut a long story short, this sort of smallish muff works for the whole century, which might account for the fact that she didn't refer to a certain decade. If you want to look at a few more pictures, I have collected some muff-picture on may Pinterest - 18th Accessoires

 Muffs in the 18th century seem to be smallish (rather earlier) to medium (always suitable) size. Towards the end of the 1780s and the 1790s muffs tend to grow up to ridiculous measurements. But also medium sized ones can be seen on fashion plates. What seems to always work is a smallish-medium sized fur coated muff.

Here are a few examples:
