Would you consider this as a harp?

That is a great find, thanks! While sorting through old bags of coppers I've always glanced in hope of finding something like that for years other than 1962.

From what I can see (and I am sight challenged), there appears to be five parallel lines. That would mimic the 'guitar' version found on the '62, whereby there are five lines of approximately the same length. I think on the 'harp' version, there are four lines of varying length, however I faintly recall hearing about some five string harps out there somewhere.

1973

Yeah, I've over looked that area for a while but recently found a dozen die clashes like that in the 1970's. The clash marks have more curves compared to the nearly straight lines on my harp.
