OT: K3 and Johnson Matchbox

[Richard Fjeld-2]

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)

Talk to Hank, W6SX.  He uses several Matchboxes, one for each band with
an automatic switching arrangement.  He's good on QRZ.

Lots of room on your desk, Hank?

I've seen Hank's setup. Not on his desk, but nicely done.

Great group!  I'd like the readers of this reflector to know that I received several replies to my post, with 12 pictures, and most impressive; three others volunteered to remove the case from their tuners to photograph the coils for me. That is a tedious job.
 
 K3KO suggested that some people would move a tap for the 30 meter band and I could test for it without removing the case.  Per his suggestion, I had a 200 ohm 10 watt resistor and tied it across the output of the tuner and tested the 40 and 20 meter band for matching to a 1:1.  It was fine.  
My first Matchbox (years ago) matched open wire like a slam dunk. This one is different, but so is the antenna. So, I needed to verify.
 
Thanks to all,

Dick, n0ce
