These are new, old stock plastic fingerpieces for morse code paddles and keyers manufactured by Nye Viking Company. These are from remaining company stock. Nye Viking is no longer in business. But now you can replace broken or damaged finger pieces on that keyer or paddle with these original, exact replacements. These are the real deal from the manufacturer, not 3D printed or other reproduction.

These fit the following key models:
SSK-001 (can be seen on the right in the photos)
SSK-1-K
SSK-2-K (can be seen on left in the photos)
SKM-016
...and perhaps others I may have forgotten.

4 inches in length. They fit either right or left side. Price is for one (1) unit. Buy two, and save 20%.
Keyers in photos are for display, and not for sale.

I've been an Amateur Radio CW operator since 1979. I love morse! See my other listings for my line of Rugged Wire dipole antennas.

I've been on Ebay since 1997, and I'm happy to answer any questions you may have.
Tnx, and 73!
