This figure is the Willow Shiner (or in Japan, Honmoroko), Gnathopogon caerulescens, model 18 and number 3 in the second series. At the original time of writing, this was one of two species out of the whole series that I didn’t have. Then I was able to get both versions at once…
Note: with two versions, I am putting up photos as side-by-side ‘galleries; with release 1 (darker coloured) on the left, release 2 on the right.
