brass arm with green glass shade mounted above, with a low wattage incandescent bulb (like 25w).

Two or three antique-incandescent-imitating LEDs. They didn't have fluorescent lamps at home back then.

Because they're dark they need direct lighting, with a blue tint preferably

Your two best options are either lighting from underneath, or from concentrated spotlights from above and away from them. So spotlights with narrow beams, on the ceiling above but a metre or so away from the shelf

Not a designer but I would suggest getting a lamp to light from above/in front and a led bulb you can change the color on to try out different colors, blue or gold color are usually decent. But having the ability to dial in the color is useful to make it suit your tastes. I've found some nice lamps at yard or estate sales for cheap.

Just a quick point for your photos in future. You probably want to try using HDR mode. HDR (High Dynamic Range) takes a set of 3 photos at different light levels and mixes them to squeeze the full range into a photo rather than having some parts completely black and some completely white. Give it a try if your phone camera supports it. You need to hold very still for the photo to work otherwise it will be blurry, but the quality is fantastic if you can be still.

One last thought- Bakelite seems to love dust. I’m going to dust them regularly, but if there is a way to light them well without making the dust show up well, that would be great.

Are you going to listen to the radios or look at them?

If you don't need to listen to them, so the glass won't be an issue, I imagine that you could put them in one of those glass-fronted display cabinets that are designed for this sort of thing, displaying china and such.

EDIT: Also, I remember reading that Bakelite does slowly break down. I don't know if sunlight accelerates that; it does affect a lot of substances. If so, you might want to keep it away from sunlight.

Yeah, sounds like it.

Extended exposure to heat and sunlight also degrades pure Bakelite faster than more advanced plastics.

Discoloration – Bakelite often yellows with age and extended UV exposure. Keeping items out of sunlight can minimize this effect.
