It is sad to think that a group supposedly interested in the history of these fine machine tools would knowingly take part in artificially driving up the price to the point where even senior fellows in the field of O.T. can no longer afford to acquire the tools of their beloved calling, putting them in a terrible bind. Unfortunately narrow profit seekers, who know next to nothing of the history, traditions, and quality associated with Holtzapffel lathes, continue to menace the future of O.T.
