Title
[D8020ZAZ], Letter from John C Henderson to Thomas Alva Edison, January 31st, 1880
Editor's Notes
Re: "Columbia" installation. Didn't specify rpm; will try 800. Suggests replacing coutershaft & belts with friction drive. How support or suspend lamp & shade? Construction of electrical mains. Who's making dynamo; will send friction clutch to them. Marg: "Better come up & let us arrange it here."
