Hello, I happily acquired a small harp tonight. The harp was made by Chris Caswell either in 1982 or 1992 and was purchased from his shop in California in 1992. It has 18 strings and is strung with wire but has no string chart to say what the first note is. Has anyone come across a harp like this? I’m seeking guidance on getting new strings, etc. to get it back into playable condition. At the moment it def. will not hold tune on the current strings but I suspect it’s been quite some time since it was tuned last. Also missing 3 strings. Thanks!
