[Elecraft] Parts ID, trimmers C21,23,32,34,44,46- K2 RF board

[Doug Faunt N6TQS +1-510-655-8604]

Hi all,

I'm back working on my A with board upgrade to B K2, and have a
question about parts ID.  These trimmers are almost identical.  They
may have been in a separate bag, but aren't anymore, and don't really
have any marks on them.  However, 4 of them are a slightly different
color from the other two, and have slightly different amounts of solder
as manufactured.  Are these significant enough differences, or should
I try to find a way to measure them?
