{Collins} Looking for early KWS-1 schematic



Could someone please point me to an early version (pre 10/58) of the KWS-1 schematic.  I am troubleshooting an ALC problem and the schematic I have (same as the one posted on collinsradio.org) is the newer version showing the Test/Key switch and no ALC control.
 
As always, thanks for your assistance.
