To me she looks like a tabbie/tortie, what we call a torbie.... The pics are fine hun!
When she first went amiss what did you do in ref to finding her? ie posters, leaflets etc? Is she chipped? Has she been spayed etc?
Have you advertised her missing anywhere else?
In the link that Janey posted below are some places where they advertise lost and found cats... Have you trawled any of these sights?
Sorry for all the questions!
