LaBonte, it's the mis-use of the term or the creation of a term that gets me going. Like the use of the Hawken name for a number of cheap rifles that bear no resemblance to the real thing save for the fact that the ball comes out the muzzle when fired. A Hawken is just not a gun made in Spain or Italy or even New Hampshire. A Carolina gun or a Northwest trade gun is a definite thing and I'll bet that we both get the same image in our minds when we hear these terms.
When we hear the term "canoe gun" we both are seeing the same mental picture, too. Now, as an admitted curmudgeon, the term seems to really set me off--like a red flag to a bull. I wouldn't want one myself, 36" being about as short a barrel as I like on a smoothbore, but if someone else wants a short gun that's their business. It's not about quality, since the few I've seen are as well made as their full length brethren.
It's got to be the name. It is catchy and is probably a good marketing tool, but that may not be the only reason why it was chosen. I am not certain how many canoes there actually were out on the plains or in the mountains, but barrel length isn't all that big a problem in a canoe anyway. Lots of horses out that way if I remember rightly. And a shorter barrel is an aid to loading ahorseback. Given all the inadvertent ways that a barrel could wind having to be cut down, the idea could have seeds in pure coincidence. 150 years later, when reproducing these cut down guns and looking for a name to call them, you would want something short and sweet that sings of adventure and the Big Sky country. Cut down trade fusil or horseback musket just don't stir the imagination, do they? Canoe gun must have seemed like the answer to a prayer.
So, it probably is a marketing term--and one that has stood the test of time. I now think that it probably isn't as cynical a creation as I once did, and I want to offer sincere apologies to anyone who may have been stung by my use of that word. Dan
