Frequency Response and Impedance curves for Classic KLH drivers

Can anyone point me to existing documents detailing the electronic and audio characteristics of individual "classic" KLH raw drivers?

Looking for Frequency Response, Impedance curves and maybe T&S Parameters that may have been developed similar to what many manufacturers provide for present day individual components. I've been searching for the last month and either I haven't come up with the right search strings or this kind of detailed info hasn't been published by anyone. I'm specifically curious about the common Model 6 screw-in woofer and tweeter, Models 17 and 20 woofers and the 5, 12, 23 tweeter but ANY other "classic" KLH drivers (1958-1975) would be interesting.

Thanks! -Tim

Thanks for the response Dswankey! I did see this thread and I'm sorry to hear that he has passed. The thread gave me hope that there might be someone with the technical know how, equipment and interest in the old KLH line that may have broken it down a little further. I realize there would likely be problems gathering data with aged and potentially abused drivers but even a couple of examples would likely give some useful info and provide a little more insight into why these ancient tubs sound like they do.

Maybe I could "commission" someone here to start with the most common Model 6 version and do the removeable woofs and tweets ... ???
