Purchased by me in the '60's. It's not new but it is genuine and I suppose there aren't many around now. It's about 6 x15mm. I haven't attempted to clean it. Who wants it ?

It's yours if you pay postage., Simplest way would be I post it to you in a padded bag. Airmail to Belgium is $A3, plus $A2 for a padded bag = $A5 or 3 euro. If you find $US4, put them in an envelope and post to me. If you are feeling generous post me a 5 Euro note.
