Some sources say this one was produced in 1949-50 before it became the Coleman 426A and thence to all the other addended letters. This one is in it's original box, so I include pictures of the box because I thought it was interesting. I especially liked the red penned note "To the Hibbards from Isaac Walton". (Though, of course, it couldn't be *that* Isaac Walton.) This one is not mine, though I was pleased to act as broker for the shipping part of the exchange between seller and new owner. Hopefully we'll see some flame shots posted after it arrives in it's new home.
