My husband purchased a black mantel clock- The E. Ingram Co on back. H.M.Hutchins Jewelers. Patented 10-1878 and 1879, is this when it was made? Also inside the back panel it has H.M.H 12-30-1914 & 3-19-1918, maybe this is when the jeweler purchased and then sold it? Any info would be appreciated. Thanks.
