I'm looking at trading for, what appears to be, a gibson archtop acoustic guitar. Im trying to figure out just what it is. It doesn't have a truss rod cover so I'm assuming there is no truss rod. From what I've read, gibson was running short on good supplies during the war and skimped on details, such as truss rods, and called these guitars "floor sweepers". The headstock shape,tuner placement, paint and body look to be accurate based on what I've seen but, I'm in no way an expert. I dont know if it could be a copy because the logo looks a little suspicious. I still plan on going for it because, the deal is good and the guy is very nice has been honest about what he has. Any help in identifying a possible model number and authenticity would be very appreciated.
