I have a 3 band Zenith with a 5-S127 number still on the chassis which is not included in any Radiomuseuam information.  It does not have the long wave band, and trimmer location is different.  The schemtaic for the 2 band model seems the closest, but had to experiment to determine what trimmer was what as the alignment instructions only had one right, and that was the BC band trimmer.  It also appears it only has one antenna trimmer and that is for the 5.6 to19MC band.
