Tops for "collet" knobs?

Hey all-
I've been hunting for these coloured tips for some knobs for about 6 months now with no luck.  I suspect I might just be looking for the wrong name etc, so if anyone has any hints, please let me know!

They are the tips for these knobs

The tops pop off so you can access the screws underneath.  I believe this is called a collet knob.  I'm looking for some coloured caps (same colours as in the pic) that are about 10mm across.  Any leads?

Send the picture to Sibalco.de and ask them if they have these. They are german Sifam distributor and offer these in low quantities.

These look more like Elma knobs to me.
Tell me what size your knobs are. I have some caps laying around but not the same colors and maybe not the right size.

EDIT: my caps are for 15mm knobs. Caps them self measure 10mm. Colors are blue and grey.

EDIT: Forgot that:

Some colors in Farnell, not all that you need but still, scroll down:

Electrochronic has them also:

Thanks guys, they are great links.  I'll follow them through and hopefully find something.  It seems crazy to spend time chasing $2 worth of plastic!

I'm looking for some tops to the knobs on my Barth Dynaset.  they look very similar but the overall knob diameter is about 10mm.  Anyone know where I can get them ?  I need 3 grey & 1 yellow.

Hmm, add me to the list. I have some Ward Beck modules that do this in a similar way.

Check the measures of the Product specifications on the Farnell link, knobs or Caps, maybe it could help?

EDIT: Ward beck and Barth Dynaset seem to be using Elma's to me, they have that tipical plastic shine while Sifam (Sibalco) is matt finish for what i've experienced.
You should have what you're looking for on both links i gave, because i don't think Elma's have changed over all these years, i could be wrong?

Electrochronic, has those 10mm knobs in Grey, seems he has some sizes in black as well, check "black knobs for other projects"
