May be of interest, I was looking to make up a trimmer tool for realignment of a Pye radio,I saw Wife's empty Parker refill in recycling and had an idea, I pulled off the end which houses the ball, washed it through with thinners to remove any ink residue, then just squeezed the end to fit, finally covered in shrink sleeve job done, will last forever or until lost.
