Hi Innes can't help with type of clip but if you read National Security Vis a Tank on Page 3 of British pens posted by Widget (me) on 21st Jan 2014 there is some good advice re. removing top of cap and you can see my before and after clip. I attempted the cap band at a later date so it matched the clip. I'm now experimenting mixing different carats eg. 14ct 18 ct., rose gold. At least I was until the 'goldy' machine decided not to work. Under investigation at the moment. I think I need a new wand this 1 doesn't get hot.
Same Greenie as FPN with an interest in Mabie Todds? Hope so. I do love my MTs. Hope you enjoy your time here. Not as many posts on here (less members) but it's the quality not the quantity that counts.
