Yes, the 103A is the Frequency Comparator; the 203A is the Distribution Amp. 
Sorry for the mistake.
The 103A manual price as listed, is $25 plus shipping.  I received 
confirmation this morning that is indeed the Montronics Frequency Comparator 
manual with schematics, so I ordered it immediately 
(http://www.manualsplus.com).  Don't know how many they have in stock.
