Gosh Wayne, i'll have to find a scanner so I can convert them from paper to electrons. I didn't take many photos and those were "pre-digital". Here are two really small pix of instruments I made though...
This one I called Fruit & Nuts; made from fruitwoods and nut woods. Mango top, Oak sides, Cherry fretboard, Lychee Nut nut and bridge, Kamani wood tuning head, Walnut soundhole inlay, I forget what else. With a 27" VSL, about 5" wide and 3" deep I built it as a "transitional dulcimer - half way between a zither and a mountain dulcimer. The shape and rough dimensions are taken from an 18th century zither in a museum collection in Germany. Instead of nearside half frets, I added a central raised fretboard - the hallmark of a dulcimer rather than its European ancestors.
Here's a really crummy pix of a replica Langeleik - Norwegian dulcimer ancestor - that I made for the Norwegian Prez of a company I worked for up in Venice, FL before I retired. Notice the wooden frets set into the near edge and the other unfretted drones. The box is bottomless as was common with Langeleik as they were usually played on a table.

I also have a suspicion that wooden pegs and piano wire strings gave rise to the use of a wider range of keys and tunings, albeit unintentionally. Although it is more difficult to be accurate with wooden pegs, a small turn does tend pitch you into another tuning unwittingly. And I'm sure that on many occasions when tuning by ear a player would have ended up with the bass a 4th gap fromthe middle string rather than a 5th and played in a 'reverse' tuning - I have done so myself!
I spend a lot of my time in the 18th & 19th centuries, studying history, so being out of date is a habit.
) plus I was being chucked solos on each tune (which I played really badly
