Hi All...1st post....I have a Guild F-20....in really nice shape and sounds great with what I feel is the original case.No scratches or splits or anything else, been well taken care of....has a low serial number...I am wondering what it may be worth...the guy I bought it from claims he bought it in New York when he mustard out after the Korean war in New York or new Jersey. the ser# is below 3000...any ideas of age or value it may have would be appreciated...Cese:smile-new:
