The A103 manual is available on the Cushcraft web site - look in 
"Tech Library -> Installation Manuals" 

> Is it the same as the A743? 

The A103 is not the same as the A743.  Trap TK in the A744/743 kit is 
resonant on 20 meters.  The trap in the A103 kit is trap TM - resonant 
on 17 meters.  The tubing is also different for the A744/743 and A103 
(different diameter and length) because the outside of the 12 meter 
trap on the A3WS is different than the outside of the 15 meter trap 
of the A4.
