Thank you for your very quick response. I was aware that Fraser and Chalmers had both an American branch and an English branch. It may well be that only the American branch merged with Allis Chalmers Company in 1901. However, the stamp mill in this case does say "Chicago ILL" on it so it must have been built by the American side of the company. Trying to research companies with international offices does complicate things! __________________________ Susan Marvin Alaska Region Heritage Program Manager (907) 586-7859 [log in to unmask] Rick Stewart <[log in to unmask] To: [log in to unmask] CO.UK> cc: Sent by: Subject: Re: Fraser and Chalmers Stamp Mill mining-history <mining-history@JISC MAIL.AC.UK> 04/22/2003 10:43 AM Please respond to "The mining-history list." Fraser and Chalmers produced all manner of ore dressing machinery. They were certainly offering stamp mills for sale in 1923 (Ref: Skinner's Mining Manual and Mining Yearbook 1923). In 1923 they were advertising under the name of "Fraser & Chalmers Engineering Works" of Erith, Kent with a London office at "Magnet House, Kingsway, WC2". At this time the proprietors of F&C were "The General Electric Co. Ltd". There is a fine set of F&C stamps (5 head Californians) at King Edward Mine near Camborne - well worth a visit.
