Dusty, thanks-- I'll edit the photo caption!
This bowed dulcimer began as a diatonic plus a couple extra frets then I had one or two more frets added before having the thing made fully chromatic.
I hate to break it to you, Robin, but I do not believe there is a 3+ fret on your dulcimer.There does appear to be an 8+ fret, though. It looks like a beautiful instrument regardless.
Christopher, I see Ken H has answered your question. The bridges on Ken Bloom's bowed dulcimers are in the same fashion as violin bridges.
Yes. This allows the bow to attack individual strings, which would be really difficult with a flat-topped bridge.
Is the bridge on the bowed dulcimer curved similar to the bridge on a violin?
No, Susie, I've never been to Louisiana. Must've been my stunt double.
