Bob, there are no copies of the Bug-n-Bass. They were all made by the same company but there were different sizes, 2 I think. Differences in hook hangers could be diff. years.
Many copies of Hula Poppers and Jitterbugs were made as well as Rebels, Bagleys,etc. If they are from the original maker, they will be marked with the company name. If not, you have a copy. They would all need to be cleaned up before selling or the price will reflect the condition.
