Here is a silver plated Hawthorne cocktail strainer marked on the back of the handle “D. P.Sullivan, Pat. Oct. 11, 1892, Manning, Bowman & Co.” The front of the handle is marked “Herman Strater & Sons Boston”. It measures approximately 6 and 7/8 inches in length and approximately 3 and 5/8ths inches in diameter.
Manning Bowman manufactured the original Hawthorne strainer for Dennis P. Sullivan who was the assignor to William Wright’s 1892 patent. The word “Hawthorne” is spelled out, along with a star, by the holes in the strainer. Mr. Sullivan owned the Hawthorne Cafe in Boston in the late 1800’s.
According to one of their ads, Herman Strater & Sons produced high grade workboards, electric pumps, bar faucets and fittings, as well as copper funnels and other bar sundries for clubs, hotels and saloons. Work boards available in German silver, planished copper and tinned copper. They started in business in Boston in 1834.
I don’t know the history behind how Strater’s name was added to a D. P. Sullivan strainer. They both were in related businesses in the same town and could have very well known each other.
There is a design on the handle which appears to be an abbreviated “Olive” pattern.
