On the Vintage Computer Forums some one has produced replacement keys for his TV
Typewriter using rubber moulds and casting resin. It looks shiny and dyes are
available...
... but you might have to machine the hole in the end for the shaft to go into..

Do the DG handles have the same problems as DEC switch handles?
(fragile pivots that break off)
I'd say the first step is what Vince Slyngstad has done with several DEC
handles - capture an accurate shape in some flavor of CAD. From there,
Shapeways or an SLA printer should make a nice, functional replacement.
SLA will produce brittle but visually beautiful parts.
SLS (Shapeways) will produce stronger parts but with a matte finish -
functionally nice, but palpably different. Perhaps a couple coats of paint
would smooth that over.
