Suggestions for HMV 101 rubber feet?

I'm working on an HMV 101 for a friend, and one of the rubber feet is disintegrating. Are there replacements available or do I need to make one out of a chunk of rubber?

I wish they were available, I spend hours making new ones! Take one of the remaining good feet, and press it into a lump of children's modelling clay (called "Plasticene") over here in England) to make a mould. It helps if you dust the foot with talcum powder first, so it doesn't stick. Brush a little oil into the mould with a soft artists brush,then mix a small amount of epoxy adhesive with a tiny drop of acrylic black paint, and using a cocktail stick, drip it into the impression made by the foot. When it is full,the top will be slightly domed, so dip a finger in talcum and very gently pat it flat. Don't overfill the mould, or the new foot will not lie flat against the base of the cabinet. Leave for at least 24 hours, and gently remove from the mould, cleaning any modelling material off with white spirit. If at this stage, the new foot appears to be too soft, then place it in a warm oven (around 100 degrees) for about 30 minutes. Use a rapid-setting epoxy, not the standard one that takes hours to harden, that sets too hard. Don't overdo the black paint, or the adhesive will never set properly. Takes one or two goes to get it right, but well worth the effort.

I wonder if black silicone would work? The real thing, 100% silicone, not a latex-silicone combination. The 100% black silicone is readily available in hardware and builders' supply stores; it comes in tubes for dispensing with a caulking "gun." I'd set up a mold in the manner that Phono48 suggests, and use the silicone instead of epoxy. Give it a good 24 hours to set up and cure, until the distinctive aroma is mostly dissipated, before unmolding it.

I just cut new ones using rubber of the correct thickness, and a punch that cuts circles of the correct size.

The problem is that these HMV feet have a built-in flange running round the top, to prevent them falling out of the metal corners, so a simple circle won't work in this case.

I just buy black rubber stoppers of the correct diameter at a hardware store, and then cut the stoppers to fit. The rubber stoppers are already tapered.
Just google "black rubber stopper" and you'll get the idea.

The rubber I use is quite soft & it forms the correct shape as you screw the metal corners down, so yes, a simple circle can work. I dont just make this stuff up
Harder rubber might need the sides tapered to fit correctly.
