Those serial numbers would make them original CLS electronics. Can't be sure unless I saw pictures of the insides, if they were modified/updated or not.
IMHO, the panels are already do for replacement. You could sure use them, but you wouldn't be hearing them at full capability.
I wouldn't pay more than around $600-$800 for them. It would also depend on what shape the frames are in and if the seller has the boxes and packaging for them.
The newer model Martin Logans are somewhat easier to setup and drive. They have integrated the woofer with the panel much better than the earlier models, (the CLS is, of course, a full range speaker).
Still there is a definite "magic" about the CLS series that nothing short of the CLX or the mega expensive Neolith can match. Once you hear them setup properly and driven with enough juice, they are hard to forgot. Just like your first encounter with them back in the 80's. That's why you're here at this juncture...correct?
