Hi I have virtually closed a deal on a pristine AV 64 in sunburst. Everything seems legit to me and the seller seems to be a nice guy, however I have a question about the stamps in the neck pocket. The guitar I am buying has 93578, looking at the AV 64s I had in the past it seems to me that the number should be 93579. Can it be related to the different finish ( sunburst vs Fiesta red) or is it a red flag? Here are some pics from the seller. Thanks.
