Got a lantern off the ebay, arrived from Spain after 30 days waiting, design quite similar to Primus 991, but definitely not a Primus one. Some solder residue on the frame waist, I believe is where the brand/model plate used to be. I checked the parts carefully, but found no information about the brand or model. Not sure whether the barometer is original or installed by previous owner. I attached some photo, hopefully somebody would recognize the lantern. Any help is greatly appreciated to identify the lantern.
