They are made by Arnold Bishop of Athens Tn. (423-745-1632) best time to call is between 10am and 5pm. If answering machine kicks in leave a message> Last i talked to him I think his job was on the road but he should get back to you. I heard that he was negociating with either bass pro or cabela's for a purchase of his patent. Haven't heard anymore on this lately but I'm telling one and all if these planer boards don't double your catch I'll run to Athens necked. You get a set of two one for the left and one for the right with instructions on how to put them on. I am the type that needs instruction for dummins and even I could do it. If you can't get in touch with him they are for sale at 58Hwy Market on the wall for $19.95 a pair. Tenncrappie
