WTB: Inexpensive (!) pair of 2.5 mH chokes (coils) for crossover experiments

For my ongoing (and, it seems, increasingly nefarious) Franken-Duplex experiments.
The 604E LF section, spec'd by Altec as "8 to 16 ohm", certainly seem to my ear to behave like 8 ohm drivers (i.e., 5 mH chokes rolled 'em off too low).
I'd like to try a pair of 2.5 mH chokes on them, but i want to minimize cash outlay.
If anyone might have a pair of air-core 2.5 mH chokes gathering dust from some unrealized project, I would be interested.
Something like this would be dandy.

Smaller gauge wire is OK (we're rockin' 3.5 watts per channel at my house); exact value's not too critical either (2.2 to 2.7 mH would be fine for my purposes)! Air-core definitely preferred.
PM me if you've got something surplus to your needs.
I figured it couldn't hurt to ask!
Thanks very much for your consideration.
PS. The Franken-Ds thank you, too!

Hi Mark,
If you're a patient man, I've got a pair of 2.5mH inductors that you can have, gratis. I believe they are 20 gauge wire as indicated by the chart from this thread.
Patience is required because they're currently installed in my SDA 2BTLs--I bought a set of Jantzen replacements, "just because", many moons ago but have yet to install them. I can likely get to this project over the week of Thanksgiving...
If someone can get you faster service, by all means, take them up on their offer.

Edit: Was there a reason that italics don't work in vanilla? When I'm pretending to know Latin, I like italics.

oh, I am patient -- and cheap! Thanks & keep me posted!
The italics thing is funny. They don't work for me, either --in Chrome.
In Bono or Edge or whatever that Microsoft browser thing is called, they're fine.
Some other folks who use Chrome report they work fine, too.
I still use 'em, I just cannot see them myself -- but i have faith that they are there.
And bold still works for everyone

Listenin' to these abominations now -- they are kicking ash and taking names.
That's a 511B horn with an 802D driver bolted to it, cowering on the floor down near the lower left corner of the photo, btw
They're no match for the Community horns and the 2" throat JBL drivers, not even close (and the 802D is a pretty nice 1" driver).
