They are in the 69&70 catalogs and are said to have working recurve limbs. If the serial starts with a 9 it should be a 1969, probably would start with a K if it is a 1970. It was many years back that I owned the Cub, I always considered it being a semi-recurve, but maybe I was wrong. I was looking at the auction site and there was a red Cub that was strung and it appeared maybe that the string did not touch the limbs, but it was hard to tell for sure.
