We use (after our insulated one had the top plastic rim break) a bodum SS liter press.
We fill not only the West Marine
SS mug, but the larger one with a collar around the neck (less substantial - much lighter then the WM - and less insulation) from each pot.
To the point that the lids on the mugs frequently overflow and spit at us as they seal...
The number on the bottom non-skid is an 11 in a circle. Inside the plastic lid filter portion, it's a 32 in the same sized circle.
Unfortunately, I can't find it in their catalog; it may be discontinued.
In any event, get a liter size and your two mugs will be full.
