How to transfer UV maps?

Because of lack of planning I ended up in the following situation.
I have 2 models with exactly the same meshes, one fully rigged but without any UV map, second has UV map and texture but doesn’t have any vertex groups or armature.

Is there any way to transfer the UV map from one model to another one?
or maybe a way to import .uv file into the model?
