PDB entries 1LYZ, 2LYZ, 3LYZ, 4LYZ, 5LYZ, 6LYZ all have the
same reference:
Diamond, R. (1974)
Real-space refinement of the structure of hen egg-white lysozyme.
J.Mol.Biol. 82: 371-391
I believe they are independent refinements using the same
experimental data. I do not have access to the journal so
I cannot verify this.

Some time ago I've heard about the idea of proposing
an ensemble of models (as in NMR), instead of a single
model for x-ray crystallography structures. If I
remember correctly, this idea has been published
somewhere. Can anyone tell me what article is that?

The earliest I recall hearing about this from was W. F. van Gunsteren,
where he used an ensemble average of ten chains instead of a a single atom
chain with anisotropic Gaussian displacement parameters. Check out:
