A 3D resin printer especially a large one could likely print a complete speaker cone. A plastic extrusion printer would leave layer lines in the cone , unless it was coated in body filler, sanded smooth and painted. Aresin printer can possibly print the cone being usable when done. Possibly even using a gold resin, however to be authentic. I'm thinking use clear and paint it. A 3D scanner could measure the cone. Only requiring some manual drawing in solid works or some similar program, to add the mounting points, then print it out. However, a simple repair using a UV curing adhesive could possibly repair the damage. Especially if a UV laser pointer is used. And the adhesive is applied to the edge of the break. Slowly stitching it back together. Maybe use something like playdough to hold the cone in position while a small section is aligned with resin on it. Then flash it with the laser. Or hold a led UV flashlight on it.
8:01 the Swedish text claims the ultraheterodyne "can not even be compared to superheterodyne or anything else ending on ..dyne" Quite a cocky advert indeed.
Very well done thanks for sharing your material on such an early venture into radio.

Love it
I want to see the gas powered radio...🙃
