[Elecraft] Main tuning knob

[Ken Kopp]

Hello all,
 
 I'm a newbie ... building K2/100 #5665.
Sold my FT-1000 to do it ... (:-))
 
 I've seen photos of K2's with what appears to be 
 a main-tining knob from a Yaesu FT-817.  If this
is correct, can someone give me the Yaesu part 
 number?  If it isn't a Yaesu knob, what is it?
 
 I have the Elecraft dimple add-on, BTW.
 
 Thanks, and ...
