[Boatanchors] National HRO bits

I'm restoring an HRO 5A1. It's in quite good shape but is missing 3 hard-to-find bits. They are: (1) the National tag from the front upper right-hand corner; (2) the Noise Limiter knob; and (3) the 10pF temp. comp. ceramic cap sitting next to the osc tube on top of the chassis. 
Would anyone have a parts unit or these parts they would be willing to sell?
A question for any HRO gurus out there: while the case is the usual black wrinkle, the PW dial is light gray, like the HRO-7. Could this be original on the HRO-5A1???

Thanks very much for any help you can give.
