I think this is produced only for ClockWorkPi. So ask Alex if you may purchase one. He is really nice though, so chances are you’ll get one without any issue, unless there is no spare ones.
As for the specific model of the screen, I am not an expert, and I haven’t found any info other than this post:
but based on this post, and based on the model number on the back of the screen, the specs, and etc., the screen is similar to this, except the cable is different (I wonder if that is the only difference, and if so, since your cable is not damaged, you may Frankenstein this screen to make it work):
