So far no one can tell me if a Gibson is considered a long box or a short. The two bottom calls are what I've entered at Nationals as a Box Call Set in the hunting calls. The problem is no one can tell me if a Gibson is a long or short box? I talked with Karen Cavender who registers all the calls for the contest, to see if I can enter them as a set or if I need to enter them as single calls? She forwarded my question onto thhe chairman of the call committee and he couldn't answere it either. He sent me an email back and said they would check it out and get back to me. He got back to me and said he ran out of people to ask. There has never been a Gibson entered at Nationals. [:D] So now we are down to what does it measure? The long box on top is 12" with a 6-1/2" cut out, the Gibson is 10" with a 6" cut out, the Turpin is 8" with a 5-5/8 cut out, a Gibson sits right in between. So I'm still waiting to find out what it is considered? At Midwest I entered it as a long box? So what do you guys think?
