Vintage parlor guitar, guessing on the brand, but it's nearly identical to others I've had, made in Korea
The label inside the soundhole only lists a model number and there is no brand marker on the headstock either. It's nearly identical to a Checkmate Model No. G235 that I also picked up right around the same time, so chances are they're related.
This one plays a little better, even though the neck is separating from the body, so it doesn't stay in tune for very long. Like every Checkmate acoustic guitar that I've ever seen, this one also looks great, which is probably the reason people still collect these to this day.
The double flowered pickguards just invoke the spirit of this one's glory days. These are purely for collectors, they don't play easy enough for beginners and they don't sound anywhere near the level needed for recording and performing.
Thanks for looking, more high-resolution pictures here.
