[Elecraft] K4 VFO A Knob size

[Gary Smith]

I have one of the apparently discontinued 
CNC machined knobs on my K3s, the one with 
the bearing for the finger dimple. I 
really find that bearinged dimple an asset 
I use constantly, especially in contests. 

The K4 doesn't come with one & I would 
like to migrate it to the K4. Are the 
knobs the same size on the K4?

Thanks & 73,

Gary
