Does anyone have one of these?
http://www.shopstanley-pmi.com/product/7213http://www.amazon.com/Stanley-Adventure-Stainless-Steel-24-Ounce/dp/B005188T90/ref=pd_sim_sg_14I am trying to determine is it will fit in this (a burner ring for my "Folding Firebox" stove):

Diameter of the hole is 3.84". I am looking for the diameter measurement of the Stanley cook pot in that long middle section, not the flare at the top or the rebate at the bottom.
I see mention of "4 inches" in some references to the Stanley cookset, but I don't know "which diameter" they are referring to, since this pot appears to have three different diameters.
Alternately, can someone tell me the diameter of one of these stainless cups that snuggle up around a Nalgene bottle (this particular one is made by GSI, but I know Olicamp and a few other manufacturers make them as well):

I am looking for a cooking vessle for my Folding Firebox stove (this burner ring is part of their "Upgrade Kit"):
