From my limited knowledge, the letters state it's a 1968-69 Cavalier (labeled X-100 in print). It would be on the lower end of the spectrum in Howatt's lineup. Still a great shooter, just not all the fancy woodwork. It looks to be in amazing condition, 20# and a lefty leaves a small market, but I can see it worth maybe $200 or something in that range. Don't remember all the rules, not sure it this is allowed, but on Facebook there's a group called Damon Howatt traditional bow owners that has some extremely knowledgeable people. Can get more knowledge there, even possibly sell if your so inclined.
