So at last I've received a replacement A5 Malden with the correct 30 mm rings. A big big thank you to Filofax customer service in UK, they were very helpful throughout this whole saga, which started soon after I bought it in London at the meet up back in March, two months ago! You can read what happened in my earlier posts.
So what is the difference between 25 mm rings and 30 mm rings?
As you can see above, looking at them like this the difference isn't that obvious is it? Which is which? Well the top one is the 25 mm ring one and the bottom one is fitted with the 30 mm rings.
However, looking that them from above like this, you can see quite a marked difference between the two ring mechanisms and why the 30mm rings will hold considerably more pages...
So I've already set up the smaller ring one with a 2011 Business A5 diary insert I picked up in UK for £1 this week in a shop sale in Heswall and I've moved the A5 fill from the smaller ringed Malden to the larger ring one. I will post an up date once both are fully set up.
