There seems to be a popular misconception that the Coleman 241G lanterns are particularly rare and/or valuable. They are quite sought after by US collectors, but I think that's just because they were never sold in the USA.
I currently own 3 241G models and 2 241A models (older and scarcer). They are fine little lamps but I suspect there are a lot more of them around than is commonly realized.
Please chime in and tell us how many you have.
What about the idea of starting a registry by model? Especially for the less common models like the 241, 246, 247, 238, 206, etc. Take the lead and start a new topic in Gallery called "Make and model" Registry, e. g. "Coleman 241G Registry" or "Primus 1015 Registry"
If it is popular, I can even create a new category called The Lamp Registry.
