Originally posted by Joseph: A Dacron string that you make would be just fine. If I remember correctly the string for a recurve is 3 inches shorter than the bow length. I think that is correct and a longbow is 4 inches shorter? It sounds like your sons bow has an endless loop string on it. It is just a different style of string that is easier to mass produce. Damon Howatt recurves are good bows. I would not put a fast flight or low stretch string on it. As far as how old it is that is hard to say, Damon Howatt bows have been made since the late 1950's. Martin Archery purchased the company somewhere along the way, I think in the 1980's and have continued producing the same bows. You might want to post a picture of it in the Collectors forum. Someone there might be able to narrow down the year of manufacture for you.
