RE: looking for an old IBM knob from a 609 calculator panel
There’s a lot of aluminum stove knobs that might fit the bill. Google “metal
stove replacement button” and you’ll see a few.

It's an unusual shape but a good enough copy for 3D printing could be done in OpenSCAD from a few caliper measurements: disk dia, disk rim height, overall height, dip angle, top paddle width, bottom paddle width, top indent length/width/depth and paddle front radius ought to be enough.

Re: looking for an old IBM knob from a 609 calculator panel
Hi Bob Even with 3d printing, you'd need to do some sanding and shaping to make it look as clean as the original. I still think casing one is the best option. If the mold is right, it will even match the surface.
