Ooo, a trivia game, that most honorable form of
were made for the armies of the great King Bladorthin (long since dead), each had a thrice-forged head and their shafts were inlaid with cunning gold, but they were never delivered or paid for;
That's from The Hobbit, Inside Information, found fair and square in the book and should be sufficient to answer the question.
But I got to wondering, who the heck was King Bladorthin and if he was so great why didn't he pick up his merchandise? The name didn't come up in the Appendixes. The Lord of Dale at the time of Smaug's attack was Lord Girion, and Tolkien mentions most of significant Elf Lords by name.
Not having time or brain for research, I resorted to Google, and found this very interesting bit of conjecture here http://www.tolkienwiki.org/wiki.cgi?FAQ ... Bladorthin
The author's conclusion is that Bladorthin must have been one of the Lords of Easterlings, who tried to resist Sauron's dominion in the East but was defeated before he could muster his armies. That is pure speculation, but I rather like it.
