The 3rd pick doesn't do them any favors. Probably get most your money back in parts.

For some reason the tops to these always look bad. Still $200 aint too bad. Dreaming of that 1200 from uncle sam.

I don't know if anybody would be interested in these silver basket MW6500's. I'm holding off because of the crease in one of the cones. I know these are hard to find though so I'm giving a heads up. $74.50 plus shipping for the pair.

This one's interesting. Looks like an old Peerless tweeter, w/o hole in dome but with flats on pole piece. No numbers but looks like could be Danish made. $28 shipped.

I noticed that the texture of the dome looked different, like maybe it was lacking in doping. Here's another one that might be Danish made. It's a 3514XXXX, but perhaps that was just Infinity's numbers vs Polk's 7514XXXX. It certainly looks just like the ones in my 7Bs, sans the hole again. I have heard it said that the hole was so that they wouldn't be damaged by air pressure changes during air shipment. Seems plausible but I still wonder.

A PR "emulates" the volume of the port in a bass reflex (BR) enclosure. The moving mass of the PR, in theory, should equal the mass of air contained in the volume of an equivalent BR enclosure's port. In practice, the moving mass of the PR is tuned with added mass* to provide the desired system resonance.
___________
* A storebought 'generic' PR often has a threaded rod in the center of its diaphragm and mass can be adjusted by adding nuts to the bolt. At least, that was common practice a decade or two ago.
FWIW, here's a passel of modern off the shelf PRs if you're interested/curious:

A very nice pair of Monitor 7's. I think these might belong to someone here.
