You're welcome, Lawrence.
I suggest you find other examples of dulcimers at a music store or at a festival, and compare them to yours.
The quality varies quite widely, from cheap cardboard kits to fabulous works of art such as Blue Lion dulcimers.
Some of us on this site recreate historically significant dulcimers of the past, so that today's enthusiasts can experience first-hand what it's like to play an old-fashioned instrument for a reasonable price.
