I got this lantern for my dad for Christmas (and his birthday, they are a week apart). It's pretty cool because it is his "birthday" lantern.
I bought it off eBay months ago. I had been looking for a while, and this was the only one that turned up so I jumped on it.
It is an A-46, which means it is an early '46 model. (His birthday is January '46.) It is an ex-Canadian Seafoam-painted 242B. At some point in its life the paint was stripped off and the brass was polished. The only paint left is on the bottom.
It was not sold as functional, but it is rare that these need more than pump leather oil and a cap gasket. I replaced those, along with the missing burner cap. It pumped up, held pressure, and hissed air when the valve was opened. Perfect.
I burned on a new mantle, filled it up with fuel, went out for a test fire, and... nothing happened. It wasn't getting fuel. So I had to give it to him in not-yet-working condition. Did I mention that I waited to the last minute to get it working?
I got it apart today and found that the needle in the fuel/air tube had some corrosion on the tip and was stuck in the closed position, so it couldn't suck any fuel from the fount. A little cleanup and we were back in business.
It should outlast him now!
