Sigg part for Coleman, but what Coleman?

This looks like a part of a Sigg kit for Coleman, but what modell of coleman? Any suggestions?

 

I believe it's for the 400. But it might be for the 550. I'll check when I get home in 30 minutes

Coleman/Sigg Windscreens
Sigg Tourist windscreen help

 

I have 2 Sigg sets with 2 different windscreens as shown in the pictures. Both wind screens are slightly different and both fit my Coleman model 400 and my Coleman model 533 (model 533 doesn't seem to be as precise a fit for the windscreen as the 400.) At first I thought they may have fit my Coleman 550, which I recently let go of, but on second thought I believe neither one of these wind screens fit the 550 if memory serves. Hope this helps

 

I have two of those Sigg wind rings,,, one came with a set of Sigg pots, one came with the 400 stove. Both fit perfectly on the 400 and on the 533. One of them is larger/wider than the other. Which is the “original”? Maybe both, maybe neither. Neither have any markings.
