Schenectady helped turn the tide of at the Battle of El AlameinI recently found a 2-page advertisement that the American Locomotive Company (ALCO) placed in the May 1943 issue of the trade magazine Railway Mechanical Engineer. In addition to manufacturing M4 Sherman tanks, ALCO produced the secret M7 Priest, which the British debuted during the 1942 Battle of El Alamein. The British and American military thanked ALCO with a M7 Day parade the following year.
I've written several other posts about ALCO's contribution to the war effort, and of course there is a chapter in my book devoted to my grandfather's time at the company as a welder. Check out the Sherman Minutia website for more detailed information on the types of M4 Shermans produced by ALCO.
