They are Frieds, not IMFs. IMF a british maker which distributed by Irving "Bud" M Fried in the US. He was a well known distributor of high end british equipmentin the early days of hifi, and while the exact details seem to be contested, at the very least he helped get the company going (which I assume is why they used his intials, rather than those of John Wright who was the main designer (though Fried claimed some role in that area also)). But IMF and Fried parted ways and Fried started his own eponymous company, most of whose products used a resisitive line, a simpler variant of the transmission line that IMF was know for. This allowed the prices to be noticeably lower, since TLs are complex to build and heavy, so expensive to ship.
Fried was a very skilled designer and had a very good ear, and his speakers were very well regarded, though partisans of IMF and TDL (its successor) sometimes slag him while defending Wright. Clearly, though, both were very skilled.
Run right over and buy those things immediately. They are fine speakers, and the drivers themselves are worth much more than the asking price. Once you've got them, check to see that the foam in the resistive line is still good -- if it isn't resilient and doesn't fit snugly in the duct, you might have a quasi ducted port speaker, and it would be worth trying to find appropriate foam to replace it.
As noted in one of the posts, you can find more on it if you search for Fried Rs. But you'll have to sort through a lot of fried, as in blown, speakers to find appropriate posts. What Bud was thinking in calling them that, I don't know.

I would not worry about the foam to much, looks like standard foam.
Even if half the units dont work, their cheap.
perhaps someone pick them up for you, or take time off!

I have JUST started listening to my new IMF TLS 50s tonight...all I have to say is, this is incredible. I seriously am blown away by the bass definition and extension and mine do not even have the original bass drivers. You must run towards these speakers.

HOORAY !...ELECTRICITY !
If anyone else has a set of the extremely rare IMF badged Model R (which were the forerunner to Fried series I Model R), how is the back connector plate labelled ? And does anyone have crossover photos ?
More discussion on the IMF badged Model R is in the 5 page AK thread..."Any Fried model R fans??". This historically valuable gem is also mentioned in AK thread "IMF owners thread!" on page 37 as posted on 6/18/2015.
I heard both the IMF badged and Fried badged Model R's both on the same day when they first came on the market at 2 different shops, and then again a few times for both. As the 2 companies transitioned, the IMF badged sets vanished within the year, and then Fried Model R series I (one) was the only badged model ongoing and later modified to series II, plus other numbered versions afterword.
The IMF & Fried R's sounded identical, with the same physical dimensions. The Fried were a bit less in price. They looked different, with the IMF model R having their typical company lighter wood, IMF front badge, and an earlier surround disc around the tweeter. The Fried R had their typical dark color wood, the Fried badge, and the later different ongoing type surround disc around the tweeter.
The op's photos are spot on, the extremely rare IMF badged Model R, which preceded Fried series I Model R. You can see the 3 lettered badge as opposed to Fried's 5 letter badge, plus the light wood IMF made cabinet and earlier type surround disc around the tweeter in his 2 fotos (log in for full size fotos).

Proud owner of a pair of Fried Model RII (with modified crossover as per Fried). I'm 6 months into ownership and they continue to wow me. I listen to a lot of electronic/synth music (along with classic rock, pop, and even country and rap). These speakers are refined beasts. I power them with a rebuilt/upgraded Pioneer SA-8800 and use a Topping D90 DAC. The Pioneer and Frieds have great synergy. Blissing out today with some deep house and trance. I measure useful output to 25hz with all the clarity and depth one can expect from the T27 and B110. Heaven!!
