Ladies and gentlemen This lamp arrived this week and it is just beautiful. I have had this one on my wanted list for a while. And I could do a local pickup. Lamp is marked AO. And the price is written by pencil on the top flaps NOK 95,50. I replaced the tanklid washer and pump leather, And fired up with an Optimus 250 CP mantle. I believe this lamp has seen little use. Gave it a clean with soap and hot water and it looks like new. Bjørn
Thank you guys It's a lovely lamp. It came with the instructions sheet also dated 1950. Will post it when I get the time to scan the papers. On the top of the box you can see Kr 95,50. Maybe that was the price in 1950. Bjørn
