Looking for a scan of the manual, or at least the schematic for the Ramsey CT-70 frequency counter.

Thanks!

I don't have for the CT-70, but I was requested for the manual to my CT-125 FREQ Counter. And, that one can be found here.  https://archive.org/details/ramseyct125frequencycountermanual3281989  Now, is that similar to the CT-70? That, I don't know. 
I was asked, yet another weird question, of how I would like to be buried, when I finally bite the big one. The answer was actually pretty easy. Face-down, like a certain historical figure in the late 1980's, (I will not mention who, but some of you will get it, and that's enough.) Why??? It would be a burial that will satisfy everyone: (1) My enemies will say that it will show me where to go. (2) On the same point, I can have my enemies kiss my butt. (3) It will temporarily give someone a place to park a bicycle. See??? A WIN / WIN for everyone.

Thanks for the link, it looks like a rather different model.

I suspect you have already seen it, but Vintage Manuals Inc. has a CT-70 manual listed. It is priced at $26, though. o.0
