Dana pens in Tel Aviv has a sale every December.
I was there today. I found a beautiful NOS Bexley button filler and bought it immediately.
I found a picture of it at: http://www.parkville...collection.html
Its an orange cable twist dating back to 1994 and is no. 274 of a limited edition of 1000 with a 14k two tone nib. Unfortunately it came without a box, but you can't have everything.
Looking forward to using it
