Yeah, the Hamers are solid bodies. They used the violin body for the size, outer curves and top carve contours. Interesting that they did that to get they close to a real one. The binding is nice, rather large in areas....has yellowed over the last 25 years and actually accents the gold nicely now.
Maybe these were also Hamer's nod to the Gibson EB1 ?
I think they only made like a dozen or so of these. I inow Mike Anthony has one, Kip Winger had one the color of mine and I have seen Jack Blades playing a sunburst one. I had heard Hamer made McCartney a lefty one but he found the boomerangs "confusing."
