This is my MSR Whisperlite International. Includes the 650ml bottle, and a bunch of spare o-rings etc (enough that you'd ever need). I used it for maybe 60 days total, only with shellite.
Note that there is a small bit of (grey) plastic tab missing from the pump...one of my mates broke that just after I bought it accidentally. It isn't an issue at all in use. I last used this thing 10 years ago, but I have no reason to think it shouldn't work just fine.
