A Closer Look at the Rijnsburg Lathe

[note: the nature of the Rijnsburg Lathe has been resolved: The Rijnsburg Lathe: Like the Sun, not 200 Feet Away]

I am still attempting to assess the documentation and authority of the lens lathe at the Rijnsburg Spinozahuis. If anyone has notions of either the historical accuracy of this device, or even the working designs of its construction, your thoughts are appreciated. Posted are two perspectives, one taken from a Spinozahuis photograph, the second is of an illustration of something of the same as found in Rebecca Goldstein’s Betraying Spinoza (2006).
