Identify, repair or replace mid range speaker in B139 based setup


I got my hands on (could not resist bringing home the famous oval driver) these speakers. Doesn't look like DIY but might be a kit.

a) If someone can identify what those, let me know. 

b) The midrange driver is all chewed up (foam gone, still runs, but broke voice coil wire when trying to remove from enclosure). Can somenoe ID the driver? Anyone out there that can refoam (and put longer voice coil wires back on)? 

c) If I cannot repair the existing midrange drivers, I need to find replacements that fit into the bracket (preferrably with their own sealed enclosure like the originals). Or else (but then would stack vertically with tweeter.

Peerless KO40-MRF.  Often used in configurations where a low crossover from the B139 was not necessary.  In those situations, a KEF B200 was the popular choice.

FWIW, the B139 is, technically, not an oval which has no flat sides.  The shape is more like a racetrack.
