Sengbusch No. 55 Self-Closing Inkstand

The No. 55 measured 3.25" x 3.0625" and weighed 1 lb and 4 oz. It was constructed of pressed glass and hard rubber or plastic. I can find specific references to the No. 55 as early as 1915 and as late as 1955. However, it is my opinion that it would have been available a year or two earlier and likely produced until Sengbusch Self-Closing Inkstand Co. went out of business.
