Despite my best efforts not to become a collector I now have nine Colemen GPA lanterns. The latest is this NTM 228E. It started out it's life in 1960 as a 220E. I bought it as a parts lantern and scavenged a few parts to make repairs on others that I have. A while back I decided to rebuild it as a 228E with the "big hat." I bought a "new" frame and collar on eBay. I was able to complete it this week when I found the correct vent. I fired it up the other night and it runs like a champ.
