Same as Massachusetts Arms Company
Page 36 of Life, Trial and Execution of Captain John Brown in 1859 reports
that the Independent Grays of Baltimore loaded two wagons with arms and
ammunition found at Brown's house. The boxes were filled with Sharp's rifles,
pistols, etc. all bearing the stamp of the Massachusetts Manufacturing Company,
When Brown was asked about their arms (page 48) he replied "Two hundred Sharp's
rifles and two hundred revolvers - what is called the Massachusetts Arms Company's
revolvers, a little under the navy size."
