Akai s950 parts

Hey I'm looking for the outer knob on the akai s950. The outer knob not the inner ring. I've reached out to a few guys online with no luck. I listed the ones i've contacted below. Does anyone know where I can find a place that could sell it to me?

I've contacted:
16squarez
vstservice
jazzcat

I didnt reach out to vintagesynthparts and syntaur because they stated don't reach out to them if the item you're looking for is not on their website.

Thanks
