[Boatanchors] Need: grey knob from the Morrow Twins

[Dale Parfitt]

I have just completed the restoration of my first set of Morrows:

Last thumbnail in the lower right

And am in need of one of the medium grey plastic knobs to get going on  the 
second set. A long shot- but does anyone have a parts rig with the medium 
sized knob?

Tnx,
