Another Times article has some more info on the Q (it is being made somewhere in San Jose), but the exact location is being kept secret. Would it be surprising if they outsourced the 7 to the same manufacturer?
"Google uses a contract manufacturer to make the Q. Last week it was being assembled in a large factory 15 minutes from Google headquarters. The company declined to say how many people were employed at the plant, which can run as many as three shifts each day. However, during a brief tour, made with the understanding that the exact location would not be disclosed, it was clear that hundreds of workers were involved in making the Q."
