I have an old acoustic Gibson that has been in my family since new, the story I was told that it is probably a 1939 as my great uncle bought it before ww2, the guitar had been past down to me from my grandfather. The only marks I can see through the sound hole inside are stamps that I believe the first is maybe an (8), then clearly see a (25a), followed by red ink pen handwriting with (26-). I’ve had it a few years I’m just hoping to find out what model and year it is. If anybody has any info I’d appreciate it, thanks
