I ordered a MSR Whisperlite a few years back and it came with a weird pot support. After trying like hell to get it to work with my Whisperlite and failed, I discovered it fit perfect on my MSR Model line up of stoves. I have no idea if this is even what it's supposed to used for. It was covered in soot and turning blueish so someone thought it was a stove accessory. I'm just wondering if anyone may have seen what I'm about to show you, before! Possibly tell me if it's an actual MSR product or if not, what it may have been originally to. Here it is. It's made of steel and a bit heavy. I cleaned it up when I got it so all the soot and blueish color is mostly gone. As you can see it looks right at home on this Model XGK II. It fits really snug inside the burner bell once the original pan wires are removed. It fits in every model of this line. The four groves and burner legs line up perfectly with the openings for the pan wires. The pot supports sit just high enough to clear the generator loop. I mean it's an exact fit. So if it wasn't made for this stove than it's one hell of coincidence. As you can see perfect fit. Like it was at home. Just clears the generator loop. Nice and wide, sturdy too. You can fit a pretty decent size pot on top safely. Remember this came with a Whisperlite. Here it is in all it's glory. If someone knows anything at all about this contraption or thinks they might, please feel free to chime in. Even if you just was to take a educated guess, go right ahead. Thanks everyone.
