Wow that is a nice collection you have!
I have two coleman lanterns right now, a 288 which I bought new almost 20 years ago and a 1929 'slant' lantern which I picked up off ebay. I'd like to add a 228 with the wide top and maybe a red. I enjoy camping and it's great to light them up and hear that hiss they make. The other coleman item I have is a 2 burner stove I use when camping (bought the same time as my 288 lantern)
I'm taking my 4 year old to a "Lantern Walk" in a few weeks... looking forward to lighting up the lantern!
I also have a small collection of kerosene lamps/lanterns that I collected as a teenager.
