The blue SCS photo you posted, from the SCS website, is of a mini SCS grinder.
(Aimless Ryan was incorrect, the first photo on the mini 4-piece gold SCS page shows a gold small, the second photo shows a blue mini)
Your green SCS photo is of a small SCS grinder.
They are different because they are different.
I doubt they care about the incorrect photos, customer service doesn't seem to be a high priority to them.
From the SCS website, these are photos of what I believe are the 4 different sizes and tooth/hole patterns, which do not necessarily relate correctly to the product pages for each model.
Mini (8 teeth/8 holes + 11 teeth)...
Small (15 teeth/15 holes + 12 teeth)...
Large (16 teeth/24 holes + 20 teeth)...
Jumbo (36? teeth + 36? holes + ? teeth)...
I don't think the design has been changed from your model, you are just confused by the mess that is the SCS website.
