Need 7A driver ID help

subkron

So I got a pair of 7As (SN 4798,4817) that I will be parting out (cabinets were very bad, peerless tweeters). The drivers are a bit of a mystery to me, they measure 6.5ohms as DCR. I basically just want to know what the driver model # is, MW65xx. Both drivers work fine and I epoxied the magnets as soon as I got them home.
