Need help identifying domed/convex knob caps for Dynacord CLS222

[fazeka]

Hi,

Have a Dynacord CLS222 that has some missing knob caps. Would like to get some so I can determine knob placement face-on. =)

Anyone know which knob caps these are? Unit is made in Germany, if that helps. Knobs were probably a European manufacturer?

At first, I thought they were Sifam or Elma but then I see that the cap is actually domed/convex and not flat. Can't find any Sifam or Elma knob caps that are domed like that.  :'(

Help?

Thanks,
Chris

It might be dificult to find the original replacement, probably is easier to replace for new knobs of your liking

they always get lost 
maybe you know someone with a 3D printer , or at least a shop nearby ?
i did this to replace a button on a lexicon pcm70 once .
once you got the measurements and cad file , or whatever you need to feed the printer with , this should be cheap enough .
i could use some , too  8)
