The one you've posted (and corrected) is accurate though. I used that one to mod my other one.

The rev. log. pot thing may have come on later versions. I know for sure that my first runs are linear.

OK, schematic updated with a few more notes. Sounds like there were ultimately a few different versions as far as pot/transistor combinations.

Probly whatever they could get they're hands on at the time.

Yeah, just like the other old wahs from that time period.

The original pot in mine measures 140K, and on my DMM, seems to be very linear. It even has 100K stamped on it, yet it dials up to 140K quite smoothly, in both directions. 

Just thought I'd post this for posterity.... I measured my OEM pot last night out of curiosity and it measured 85K. It's a linear pot and personally I think the sweep is just fine.
