Come to think of it I don't have the trailing dot either.
I thought the dot was to terminate domain name qualification for forwarder
records.
zone "174.50.10.in-addr.arpa" in {
type master;
file "db.10.50.174";
};

My pointer zones are more like
Zone "28.66.136.193.in-addr.arpa.", I've never had that leading "0-"
Is that typical? What does it do?

That confirms that the origin is in fact "0-28.66.136.193.in-addr.arpa."
(Save for any typo that I may have introduced.)

So when your system(s) try to do a reverse DNS (PTR) lookup for
193.136.66.1, it will actually do a PTR lookup for
1.66.136.193.in-addr.arpa. and fail because you don't have a copy of the
66.136.193.in-addr.arpa. zone file locally.
At least my understanding is that you have a copy of your forward zone,
and your 0-28.66.136.193.in-addr.arpa. zone. But you don't have a copy
of, nor access to, the intermediate 66.136.193.in-addr.arpa. zone that
references the 0-28.66.136.193.in-addr.arpa. zone.
Does that help?
Please feel free to ask additional questions.
