This is the tube assembly, including a shaft, for a Springfield - style Newtonian telescope with an equatorial head and 8-inch mirror optical assembly. The manufacturer is unknown, but the design is a faithful rendition of Russell W. Porter’s design and instruments made on that design by John Pierce in the 1930s. Mr. Steve Smith, the donor, reported that his uncle, Harvey L. Walsh, found this telescope on a Virginia farm during a trip. He does not know when this happened or where the farm was. Walsh purchased the telescope and then restored it.
Gift of Stephen T. Smith.
