[Elecraft] K2 RF Capacitor ID

I'm having trouble identifying a few capacitors used in the assembly of the K2 RF board.

C72: "271"
C45: NPO "1", black top
C33: 2.2pf "2R2" or "2"
C198: NPO "27" or "272"

What I have:
a blue "010"
a blue "030"
a yellow "270"
a yellow "229"

I suspect the "229" is a 2.2pf capacitor for C33.
The "270" could be 27 or 270pf, but I'm not sure; it might be for C72.
The "010" could be the 1pf for C45, but it doesn't have a black top.
Could the "030" be for C198? This suggests it could be: http://www.elecraft.com/Apps/caps.htm

I'm having trouble measuring capacitance for these tiny capacitors. Values are all over the place. Any suggestions for verifying the values and positively IDing them?

Thanks,
