Each of the other band trimmers are located at the rear of the KWM-2 beneath the slug rack. My 1978, 9th Edition of the Rockwell Collins Instruction Book references FOUR "C"(14) trimmers in paragraph4.5.3.d on page 4-6 and additionally references three trimmers located below the chassis, see para 4.6.5 "RF Circuits Alignment" on page 4-9. However, I have not been able to locate these in the photos included in the manual. Admittedly, I have not had time to get the rig out of the cabinet yet.

Last month on this list, Henry - G3GIQ (Henry Lewis
<henryflewis at btinternet.com>) recommended a CD with many more pictures
of the KWM-2 from DW Holtman WB7SSN. Shown at
http://www.heavymetalradios.com/KWM-2ACD.html It may be of help. I
haven't seen it.
