Back in the 50s and 60s, the perfect scale 30mm which in the end never really caught on except in a back handed fashion when 25mm transformed into 28mm.

The Scruby figures are pretty simple and rather plain.  They have a toy-like appearance and the poses seem a bit stiff but overall they are respectable figures.  There is not much surface detail but enough to allow a reasonable paint job especially on figures this large.

One thing that should be apparent is that Jack Scruby offered a lot of historical ranges in a lot of different scales.
