Hammerhead looks a little bit sun bleached too unless it's the flash. I'd imaging somewhere around £130 might be about right depending on the litho tear or other defects.
I suspect that £130 is about right as the last post, but will come down to how badly or not someone wants it.
Got to admit I'm after a ESB Hammerhead my self, so was reluctant to give you a first price.
Perhaps pictures in day light (difficult at this time of year) may help the cause?
