You know those “metal pocket” things? Most are stamped “Swan” but you occasionally see Conway Stewart ones. Andrew Hooper sent me photographs of a rather different one that has come his way.
I’ve been racking such brains as remain to me, trying to think what “AN or NA” could stand for. I can’t think of any pen company with those initials but of course I may be missing something obvious!
The metal pocket came in company with a Swan eyedropper filler, probably a 200, which suggests that they have been together for a long time.
With thanks to Andrew Hooper for photographs and information.
