There should be a little white strip somewhere on the cable that Identifies the sensitivity of your pair.
No pics of the 'windscreen' side of the mics bodies, though. Is the foam protector intact?
Looks pretty clean actually. You ought to be able to get these up and running with any recorder that provides plug in power.
can you share a picture of any damage to the cables, and the front of the mics?
Definitely keep them! You can get these working with a little help.
