1978 RCA VCT200 needs a knob

[pac.attack76]

I originally came across this vcr on craigslist along with a Zenith b&w set for $125. The ended up in a landfill because they didn't sell and the owner said they were in the way. They were good enough to direct me to where they went along with a phone number. I was able to get them but in the process, the one knob on the front was lost and the yoke on the TV was slid back and rotated. I fixed the TV but now I'm curious as to where I would get a knob for the VCR.
