Tannoy HPD 315 A dual concentrics
I have a pair of these in Devon cabinets, the surrounds are totally rotten but the coils seem fine. re-cone kits are £150ish each in the UK but I'm confident you could source replacement foam surrounds and do them on the cheap perfectly well.
If anyone is interested in them in their current state (rotten surrounds, cabinets are quite rough) then make me an offer (cash of kit for swapsies, I am looking for tweets or maybe compression drivers at the moment), if not I'll probably replace the surrounds with a generic foam surround and have a play with them and then sell them on with the new surrounds (I'm 99.9999% sure she who must be obeyed will not have 12" drivers in the living room, the 6 1/4" C-quenzes got the ' they are quite a bit bigger than the old ones' comment with in seconds of them getting through the door).
Edit: I'm after some transformers actually for a small valve guitar amp, 6V6 power tube so mains transformer 240V primary 325-0-325V 5V and 6.3V, and speaker transformer, 5000Ohm primary 4or8ohm secondary
