Just took a look - so many choices in 1/33. Why 1/33?? Is this supposed to be a compromise between 54mm/1/32 and 1/35?
According to the list of scales over at Wikipedia 1/33 Is a scale for paper model airplanes like paper on wood which would include a lot of World War One types?
54mm is usually 1/32 or even 1/30 depending on the figure (top of head or eye level) so this is getting even more confusing.
Maybe 1/33 Is for Verlinden 1/35 scale giants.
