I need some help identifying this acoustic guitar.

Some background: my father, who constantly mixed up his guitar collection, passed away last month. Most of his instruments are identifiable, but this one — which is one of two I will keep in his memory — remains a mystery. To be clear, I have no desire to part with it, but I would be very thankful if anyone can help me figure out what it is. It is special to me for my own sentimental reasons (it was the one he was playing most when he passed), but it would be nice to know something about the instrument itself.

Here is a link to some photos, and a video, of the instrument:

Thank you so much for any help you can give.
