Hello I found this AGM lantern for sale for $30. It appears to be a model 278, but I couldn't find a number. It's in really rough condition, but seems to be complete. There are two soldered spots on the fount. No idea if it even holds pressure, but is it reasonably priced for the basis of a restoration? Or is it too far gone? I've done some Coleman units in the past and some stoves. Is the AGM parts network sufficient or hard to come by? Is there anything else to look for to ID it? Thanks for the input.
