I have a Eros 612 which is also known as an Eko Ranger 12, and you may have guessed is a 12 string. The neck on this guitar is wider than a standard neck and the guitar plays fine as a 6 string.

These guitars were made in the 60's & 70's, have a great sound. There seems to be one or two on ebay at all times in the uk, and they are not expensive. A hidden gem of a guitar if you ask me.
