That does look odd, and would be a bit tricky if you didnt have the VOR working to help you track the arc.
Agent 86, your approach is different (and easier); the NDB and the DME are (vitrually) in the same spot, so orientation would be much easier than the Flickr approach.
At a quick glance I would guess that it is a VOR NDB DME approach as all three of those are required ground aids.
Doesn't say VOR is required although obviously, for the arrival at least, you'd need it...
