Nick,
Ignore the body color on the chokes - while the body color may have been
a valid identifying characteristic at the time that phrase was put into
the manual, it is not a good indicator in the long term - the body color
can change at the whim of the component manufacturer and may change if
the component vendor is changed. There is an effort in place at
Elecraft to eliminate references to component body color as an
identifying parameter, but unfortunately, that will appear in future
revisions of the manuals.
The only identifying characteristic that can be trusted is the color
coding bands - for 100 uH, the color bands are brown, black, brown.
Select the smallest (physical size) one for use at RFC15 and use the
larger bodied ones for use at other locations - if there is no
difference in size, then either one will do for RFC15.
For RFC15, you will have to form the leads to fit between the solder
pads - it is OK to form the leads back alongside the choke body. Do not
bend the leads sharply up against the choke body with a tool - form them
with your fingers. If too much pressure is put on the leads, the wire
inside the choke can separate from the leads and lead to a damaged
component.
BTW - Green, brown, Green would be 5,100,000 uH (a very large choke) -
you must have the body color confused with the color code bands on the
choke.

I am having the same problem identifying components as well. I have
the larger tan bodied solenoidal but I also have a sub-minature tan
bodied solenoidal but it is colored green-brown-green.
Does anyone know what this green - brown - green one is for?
