I ran a Google search on the term "pre-factory" to try and determine why so many people continue to use this term incorrectly (especially on eBay). I found links to a lot of bad info and was surprised that this forum didn't pop-up in the search results. This thread has been created in the hopes of getting the discussion picked-up by more web browsers and bring an end to the misconception.
For the record:
There are only about 80 true pre-factory PRS guitars in existence. I called Paul about a year ago and verified that number. They were all made prior to mid-1985; when PRS Guitars was formally launched. True pre-factory PRS Guitars are quite expensive - ranging from $20k to $160K (and growing). If your PRS was made after mid-1985 and has a serial number of any kind on the back of the headstock (or back-plate for CE's), it is not a pre-factory PRS.
Most pre-factory guitars were built in Paul's small workshop that was located at 33 West Street, Annapolis, MD. Guitars made in the Virginia Avenue factory between late 1985 and 1995 were initially carved out with dupli-carvers and jigs and then finished by hand. Guitars made in the Stevensville factory are initially carved out by a CNC machine and then... finished by hand.
