Morse Code Key Replacement Knob

This is a replacement knob for the J-38 and other keys. The knob dimensions are 1/2” high and 1” in diameter, and are tapped for 8-32 screws (Included).

These knobs are printed from PLA and drilled/tapped by hand in the USA.

I could not find a reasonably good copy of the original WWII drawer pulls used on vintage keys, so I designed these.

*Photos show this knob compared to a 1940’s injection molded “OEM” key knob.*
