At one time, maybe they still do, TVC (Traverse City) had an NDB
approach off what was also the LOM on the ILS. Of course it was
pointed in the same direction as the ILS, but you could do a circle to
land off it.

Until recently (it was still there in 2005) Fort Collins-Loveland
(FNL) had NDB 33 and ILS 33 approaches. The circling minimum for the
ILS33 was 484 ft. agl, and for NDB33 504 ft. agl.

I don't know when the NDB33 approach got decommisioned, the COLLN
NDB/LOM transmitter is still there.

However, Greeley-Weld Count (GXY) has a fairly new NDB 34 approach,
based on the BUFFS NDB/LOM for the ILS34 approach. Again, the
circling minimums for the ILS approach are lower than those for the
NDB.

I assumed colocated ILS and NDB approaches were not uncommon.
