[Elecraft] XV432 - Is L19 red,orange or yellow?

Hi folks,

I'm working on my XV432 kit this weekend.  I ordered the high accuracy 
crystal and the crystal oven options as well.  I'm on page 31 of the 
XV432 manual, where it is asking me to locate L4 and L19 for 
installation.  I see that L19 appears to get replaced when installing 
the high accuracy crystal option.

The manual says:

L4 has an orange body with four turns.  (It looks red to me and it has 
3.5 turns, close enough I guess)
L19 has a yellow body with four turns.  (I count 4.5 turns, _definitely_ 
one more turn than L4.  At least it's yellow)

The installation instructions that come with the high accuracy crystal 
option say to remove L19 from the circuit board.  Since I'm just about 
to install it this seems like a good time to make the substitution.  
EXCEPT, it says that L19 has a RED plastic coil form, not yellow like 
the XV432 manual says.  I do note that the substitute coil that comes in 
the high accuracy crystal option is yellow and has exactly the same 4.5 
turns as the yellow bodied coil called L19 in the XV432 assembly manual.

I assume the error is in the instruction sheet for the high accuracy 
crystal option, and that they meant to say that L19 is yellow and not 
red.  However, I'd feel safer if someone who has built one before could 
kindly confirm this.

The second thing that bothers me is why does one 4-turn inductor have 
one more turn than the other 4-turn inductor?

Any assistance will be gratefully accepted.

Thanks and 73,
