I've acquired a Sigma with the sideways M....the paper label inside where the DR7 can barely be seen....and the serial # 9654 is clearly visible...Really don't know what I have, but I have a Martin and this outfit sounds an awful lot like the Martin...except I haven't put new strings on it yet.   Any ideas about the age...the worth...etc...
