Herbert and Themis,

I believe the problem was a flag in com.apple.FinderInfo. Herb's command shows a lot more metadata, but not the full contents of this one small piece. The piece only has 32 bytes. But one of these, I bet, locked that file. 

The question is how it could have been set. I don't think any modern software touches that information, so it probably comes from long ago, or an app that is long in the tooth.
