I've got an old beat-up Waterman 52 (faded, cracked lever box, no clip) that has a great semi-flex nib. I'd like to be able to carry this pen in my pocket for everyday use, but the lack of a clip makes it a bit risky for me. Does anyone know of a source for those add-on clips that often appear on older BHR pens? The ones that slip on to provide a clipless pen with a clip? I'd love to have one and bring this old warhorse back into the game. Thanks.
