WTB Knob for 1984 Electra Westone Phoenix

I just bought a 1984 Westone Electra Phoenix.  It is missing one of the black aluminum knobs which are flat on the top with a dot, and the ridges down the side.  The top is slightly wider than the bottom.   

I am also needing a trem arm.   (I know other arms would fit but an original would be really cool.)

Thanks for your help guys.  These are really top quality guitars.

Stewmac or similar for a "bar, 6mm imported" as to try and get an OEM bar is to know frustration.... as it is to find a Switchmaster knob!! You're gonna have to keep a weather eye on the internet auction sites as I suspect those of us who have a few knobs spare are hanging onto them... "just in case!!" 
And the alloy ones are very uncommon....

OK... what you got?!?

Thanks Corsair.   Original is always nice, but I will go with replacements in the meantime.  Who knows I might find a Unicorn.

In the meantime, I am out to look for a few more Westone Guitars.  I am really loving the Phoenix.  What a nice guitar.

Later to be known as the Spectrum. And yes it is!

So? Do we get to see it? Pix?
