G-101 help

I just got ahold of an old acoustic 3/4 size guitar, it is in good condition and surprisingly sounds pretty good, I was told that it is very old, dont know but did not give but $15 for it. Any way all it says on it anywhere is inside the soundhole it has G-101, I think they were made in Poland but thats it. Does anyone else know anything or knowwhere I may be able to find something on this. Thanks
