Citação: "Dejan"Then - if not variants - what? Shouldn't they be somehow marked differently?
It depends if the differences are "huge", the KM normally made either a new sub-number or a completely new number, if the alloy changed, then a letter was added to the existing km#.
Since Krause has stopped giving the numbers, we are really in a mess!
