After examining the photos I replied:
I have one of these.
Sorry to say that your guess is correct.
These were kit-built in the 1960s or 70s, so every one is different in quality. I generally see them go for $35-50.
In fact there's one here:
https://shopgoodwill.com/item/145751761Mine is unplayable because the fretboard bulges under the second or third fret. I don't know if it was mis-built that way or warped eventually. I MAY remove the frets and sand the fretboard flat, but that would be because I hate to see ANY musical instrument go to waste, not because it has any intrinsic value.
In other words, your father probably picked this up to experiment with. If he'd taken dulcimer seriously, he would no doubt have replaced it.
You could consider keeping it as a decoration, or if it is playable, you could keep it to learn on yourself. Dulcimer is fun and easy to learn.
Hope this helps,

I appreciate your time.
I have a pretty good eye for detail and see some spots on the unit that are not built well, so I figured it
was not of high quality.
I have so many other things that belonged to my father, that my brother and I have decided to give it to a friend since
it is not worth much. She can learn to play it or hang it on her wall.
(My brother and I have 7 guitars, bass amps, reel-to-reel tape recorder, recordings of his bands, etc that were his
and trying to decide what to do with everything is a bit overwhelming.
He had owned a music recording studio for 20 years)
I greatly appreciate your help and will refer people to your site if I am ever asked about a dulcimer!
Have a great day!
