i found that the lid from a Trangia tea pot fits the 123 pot just right.now i use that pot for making minute rice as a pot with a lid makes the rice come out right.the lid from a large Trangia clone tea pot switches places when i need a tea pot with a lid on hikes.that lid will also fit the cup on the Swiss "ranger stove"
a good gear game is finding a pot that is just the right fit for the 123.i was using the square Coleman kit for awhile as i could fit more stuff inside,like the 123's pot and lid combo and some odds and ends.
