Yep. You can find them on Ricardo though quite easily, and I've seen them at the Salvation Army too. I think there was a Coop promo at one time featuring them. I have a medium size one and it compares well to All-Clad and Kuhn Rikon that's in the kitchen.
Yup. I was going to say they don't make them anymore. I have a pressure cooker from 1985! I love it. Not too long ago, it wouldn't pressurize. I was looking to change the rubber thing & was really sad to hear they didn't make kitchenware anymore. Luckily it started working again. But if anyone can find & send me the rubber replacement thing, I'd send you some dulce de leche!
I doubt miniMia is still searching for the Dichtungsring after 10 years but in case anyone else is looking for a seal for a Sigg pressure cooker this one from WMF is being advertised as fitting, also saw someone confirm same on a forum. The 22cm is currently rarer than unicorn sweat; Galaxus are quoting feb delivery, I think I just ordered the last one in Switzerland.
I don't want to come over as some sort of pressure cooker nerd, but for posterity; the above gasket does not fit a Sigg pressure cooker but the Kuhn Rikon part number 1501 worked perfectly as a replacement on my Sigg cooker for Sigg part number 0201.60
Can't say much about the pressure cooker you got there. Although a few times a month I like to use a pressure cooker.
Got an Italian made Mepra 1950 manual pressure cooker here along with a fancy Instant Pot electronic pressure cooker, ordered from Ama - UK a few years back. Both are wonderful for rice and potatoes, which I always struggle to get just perfect; as well as practically anything else.
Sigg Kitchenware seems to be a blast from the past, we have a couple pieces. Sigg Stainless Steel "Las Vegas" around 2.5-3 liter sauce pot and around 5 liter stock pot. Both pieces have taken a fair share of hardwork for the last 5-6 years, since I love to cook. My spouse had them for years, probably 20+ before I moved here. They really still shine great though and considering the age could still fairly be rated 9 out 10.
* Wish I could find such a great find of some more SIGG kitchenware at the local thrift store like Brocki but never have.
