Those jackets look like they could be same pattern to me - only the waist varies for whatever reason. Patterns always vary by half an inch or so that's almost inevitable. Mass producing affordable jackets is not a science, nor does it ask for artisan precision. Machinists at the factory sometimes work differently maybe this is why your jacket is 5 cm narrower. I have also noticed that sometimes Cockpit mislabel tall jackets as regular and visa versa. I can't imagine that the owner would know the measurements from memory. That's pretty micro. Most people she deals with will ask for a large, medium, a 42 or a tall jacket and that's that. Being anal about measurements is a more recent preoccupation and still only applies to a small percentage of buyers at this end of the market. I do know that after talking to one of the Cockpit sales guy for a bit last year, he said that sometimes people ask for trim fit and there is no agreement as to what this means so they struggle with the term. The sales guy had no conception of how shoulder width changes the look and fit of an A2 jacket and thought that a 18.5 inch shoulder belonged to a size 36. Additionally, many of their customers are middle aged civilians with weight issues so a precise fit is really a priority. "Can I do up the zip over my stomach? Yep. It fits." Done.
