I have seen pictures of a pick gun a guy in Europe ( Dutch or Danish, I cannot remember ) modified so that you could switch between having the needle strike up or down, he modified it to deal with the pin-up and pin-down cylinders he has obviously encountered in his European lock travels.
It is in part 2.3 of the following pdf file link. The document is on bounce or bump keys but has a picture of the gun and a short comment. By the looks of it, I would say it was a Majestic brand.
