I am selling off my "stash." As requested by the mods, I have consolidated to one thread. I hope this is satisfactory. (For what it's worth, I am not a commercial business. Like most of you, I am just a hobbyist with an obsession and hoarding mentality. 
)
I also solemnly swear that I will not "bump" this thread, but I will update it periodically as new things are dug out of the speaker hoarding dungeon I call "my workshop." Every mad scientist needs a lab or a workshop.
Thank you all! I truly appreciate all of the folks who keep this buying and selling forum up and running, friendly, and productive.
Cheers!

Up first!
Peerless/Advent 5/8" dome tweeters. I have 40 pairs available. Maybe use in a line array?
They are compact and very similar to the Advent Baby II polymer dome tweeters. They were used on the newer Advent "Millennium" series speakers and they sound very very good. They have a mesh screen with phase plug mounted behind the screen. They are 8 ohm, Here are the stats:
Fs = 1342 Hz
Re = 5.89 ohm
Zmax = 8.59 ohm
Qms = 1.104
Qes = 2.408
Qts = .757
Le = .079 mH @ 10 KHz
Great for DIY or replacements.

Minebea/Onkyo/AR Dome Tweeters $40/pr shipped.
I have about a dozen of these tweeters. . Used on the AR XP Series, which are totally under-rated speakers, IMO. I have the ARXP62 bookshelves and they hit WAY above what the market deems their value is.

AR Argon/Recoton 1" textile dome tweeters
$40/pr shipped
These tweeters are a bit of a mystery, but they measure well and sound amazing. They are Italian made by Argon, which was a division of Recoton. I'm keeping a few of these for myself, but I have about 3 pairs available. They were also meant to be mounted under a decorative flange or acoustic foam, but frankly, they don't need it. They sound great "naked". Unshielded also.
Measured Specs (YMMV):
Fs = 1137 Hz
Re = 6.56 ohm
Zmax = 10.18 ohm
Qms = 1.763
Qes = 3.200
Qts = 1.137
Le = 0.079 mH @ 10 kHz

AR VP Series 1" soft dome tweeters $40/pr shipped
These are 4 ohm nominal tweeters. Slightly higher Fs, and shielded magnet.
They were used on the AR VP Series speakers and typically were paired with smaller cone drivers in an MTM arrangement with a higher crossover point. The face plat is also designed in a semi-horn loaded fashion and was meant to be rear mounted and/or with acoustic foam around the edge. I have about 10 pair of these.
Measured Specs (YMMV):
Fs = 2153 Hz
Re = 3.54 ohm
Zmax = 4.72 ohm
Qms =1.195
Qes = 3.580
Qts = 0.896
Le = 0.035 mH @ 10 kHz

Hi all!
Adding an item or two to this list.
AR 10" shielded woofers. Poly cones. Foam surrounds are in excellent shape. Great for use as a powered subwoofer. Relatively low sensitivity of around 87 dB. Shielded.
Here are the measured specs (YMMV)::
Fs = 30.95 Hz
Qms = 3.277
Vas = 68.49 ltrs (2.419 cu ft)
n0 = .26%
Mms = 64.5 grams
Re = 3.87 ohms
SPL = 86.31 db (1w/1m)
Piston Diameter = 209.6 mm
Zmax = 21.13 ohms
Qts = .601
Le = .362 mH
These speakers can be found in several of AR's later series including the PS, S, HO, and AW Series. They are ideal for a sealed enclosure of approximately 1.8 cu ft. But they are versatile and I have run simulations with ported enclosures too.
For you distributed bass or DIY guys, these would make nice bottom end drivers with a low <200 Hz crossover point.
$125/pr shipped to your door. I have multiple pairs available.

Quick update, only qty 3 of the Peerless 831773 woofers left, and qty 3 of the Peerless 831791 woofers. According to the NHT rep, they were supposed to have the same specs, but different basket flange. The cone assembly and magnet look to be visually the same. Make me an offer for all 6 and experiment!
I measured one of mine and this is what I got:
