About three years ago, I picked up a used "MSR Wisperlite" for a great price. At the time, I was not aware of the difference between the classic and the International versions of the stove. Since purchase, I have only used white gas as a fuel.
As far as I can tell, these two stoves are nearly identical. Current diagrams available on the manufacturer site show slightly different designs of the stand, but this may have been changed over time. My stand is wire, as opposed to what appears to be stamped aluminum on the current version of the International.
The one notable difference between the two models appears to be the presence of a metallic wick in the priming pan on the International version.
Given that my stove has this wick, I suspect that I have an International model. Is there any way I can confirm this?
