Apologies if this isn’t the best place to put this thread, mods feel free to move if necessary. Picked these two sets up a few days ago on the local (Seattle) Craigslist. Two complete (I think) Sigg tourist sets including a Svea 123 and a 123R for less then $50! The one on the right is a little beat up and well-used, mostly the frypan/lid is dented, but I think they will both clean up nicely! One of them came with a pump and pump cap that I haven’t seen before, it has a hex head fitting to access the srv. The knurling on the side is also different from all of my other caps. Anyone have any info on this cap? I included a photo of it with a standard cap for reference.
