Where to Recone a Celestion Speaker?

Hi S.L.F. Thanks so much for your reply.The speakers a vintage Celestion Blackback G12M 25 watt 16 ohm 75HZ Rola.Theres some numbers on the meatl -T1221, JL11. I took it out the cabinet, and its hard to believe theres something wrong with this beastie. doesnt botom out or anything, no scrapes or rubs when gently pushing it in. Its such a sweet looking speaker-those old vintage real cork gaskets and the heavey ribbed paper cone are awesome. I have another cabinet with g12-65's, and they are great, but not the tone of these blackbacks, thats for certain. I have three in my cabinet aqnd one reish greenback made in England, and would give my left nad(not the one I have left, the one opposite from the right-lol) to have another Balck or creamback from the 70's. I checked inside the 4x12 marshall cabinet, and the brace right near where this speaker is mounted is loose. Is that the buzzz i heard? I will ahve to play this speak thru a 1x12 cabinet to see if its really in need of recone. I would appreciate knowing any info. on the guy in san Diego though in case I do need this blackback , or another one reconed.
