A pal has recently bought an old Sigma DM-4 acoustic guitar, s/no. 90090097.
There is an internal 'branding' - no paper label.
Significantly, it has what appears to be a propeller inlay marking at the 12th fret.
Allegedly, it is in excess of 20 years old?
I am trying to find out as much info about this particular guitar on his behalf - any info would be much appreciated.
