Happy to help. Here, Silvia always adds confusion to the mix because it depends entirely on whether the importer or retailer left the original Italian market filters on OR changed them over to Australian/export market filters. The "as imported" Italian market filters are indeed a single and double, where the single (8 grams) is half of the double and doesnt require a change in grind, but they are smaller than we use here for our larger coffees and as already stated the export single is 2/3 of the corresponding double requiring a change of grind... The explanation can be confusing, but its simple enough in real terms... The original (Italian market) filters have "Rancilio" stamped on them. Anyway as you have changed whatever the machine came with to some other aftermarket stuff, I guess it doesnt matter as long as whatever you do now works and you understand why (or why not ;D) Cheers.
