According to Martins wonderful whisky-file site there were 2500 of the American release but no figure for the other two releases , I've got bottle 2204 of the 55.6% release (unopened , waiting for my 50th birthday or Harrys arrival on Islay , which ever comes first....) so it looks like there were at least 2500 of them as well . A small amount of the american release (54.7%) were returned to the distillery 3 or 4 years ago because the yanks didn't want them , needless to say they were eagerly snapped up by people with good taste......

One shop in the US was also selling them off cheap to shift them.....
