[WTB][AU] Franklin Christoph Nuclear Green pen

It's a long shot but I thought I'd give this a go.

Prefer a pocket 20 but will consider other options, ideally with a clip. Not fussed about the nib size, would like at least [B] condition or better. Shipping to Australia. (As a guide, my past purchase here from CONUS was +$20 for international shipping.)

Please send PM if you've got any leads, thank you.
