[Elecraft] OT: K3 and Johnson Matchbox

[Richard Fjeld]

I use open wire feed line with a Johnson Matchbox.  I'd like to verify that the taps on the coils are original. (I saw solder on one.) When these are purchased used, one never knows if it is in original state.
 
I've been trying to find a source where I may find detailed pictures of the coil to use for comparison.  So far, I haven't found what I need.  Any help?  (This is a 275 watt model)
