Can anyone give me any information on the Clark Irish Harp company? I have one which was bought in a so-called curiosity shop, and the dealer there said it was from the 1820s. I don't know anything about the company or its founding, but I would have guessed from looking at it that it's more likely from the late 19th century or even the early 20th. How long was the company in existence? Are there any features I should look for that would help to date it?

I was just now poking around on some harp sites but I wasn't turning up anything useful so I figured I'd try Mudcat, since in my brief tenure here I have never been let down once with what I thought were hopelessly obscure queries.

Thanks, and happy new year too! Margaret
