I'vebeen chasing around the net, and it is clea rthatb the term "Angelica" has been used at different times for very different guitars which have no connection with each other, as well as for other instruments which aren't guitars.

The one I've got is a Jumbo flattop, and I'm holding it in this picture. Nothing fancy, but very pleasant to play. The one Allan found the quote about sounds as if its the same variety.
