Well in this day and age where guns and ammo are "hot items", it would seem unlikely that an established manufacturer like Colt would go belly-up. But anytime you see their bonds trading that high, it means bond buyers are skeptical. And if you think Pythons are expensive now, they would bump up another 20% if the company ceases to exist, even though they haven't produced them in years. The collectible value would skyrocket.
