Forwarding doesn't work...?

I'm working on a customer configuration that I replicated, and he uses a
slave server to slave one domain from a master and uses forwarding to
the master for all other queries that come to the slave server. Queries
to the slave for names in the slaved zone work, but queries to the slave
for names outside the slaved zone (which the master should "know") don't
get a response (forwarding isn't working?). I'm wondering what I need
to look at here...
The relevant slave zone portions are:
options {
recursion yes;
forward only;
forwarders {
9.5.56.157;
};
listen-on port 54 {
9.5.129.153;
};
query-source address * port *;
};
zone "S020AG00.BRANCH.AGF" {
type slave;
masters {
9.5.56.157;
};
forward only;
check-names ignore;
dialup no;
max-transfer-time-in 60;
notify yes;
};
Query to master for a domain shows it exists:

Query to the slave give no answer, althought the forwarding is setup:
D:\CheckOut>dig @rchmach -p 54 s02tb100.branch.agf.
