Today I found this stove at the flea market. The only reference I found on the forum:https://classiccampstoves.com/threads/olso-light-company-ltd-1922.389/ It seems to be a British stove. After cleaning it, the words "Made in Austria" emerged View attachment 348791 The trivet fixing system is also interesting: it locks by rotating it clockwise.
@Bebo What a great find! The locking trivet is a brilliant feature. It amazes me that such things are still out there ready to be discovered at a flee market of all places. Congratulations! Ben
