Should the 20 button Lachenal Anglos have leather on the bottoms of their pads?

Pictures of your concertina would be nice.

Here are a few that were sent to me before I acquired it. It’s a later year, serial #147590.

Are you sure that is only 92mm wide? This is a 10 button 92mm miniature:

I apologize for my apparent misuse of the term. I assumed "across the flats meant the length of each side of a hexagon. Clearly by your example, this is not the case. Am I to assume then, the term refers to the width of the hexagon?

Yes, "width across flats" (often abbreviated to AF) is an engineering term that means the distance between two flat parallel sides.
