Vintage Carl Zeiss Jena Comparison Spectroscope Early 1900’s. This is a great looking spectroscope in it’s original wood box with original Z key. Please see all photos for what is included, there are missing items. This was sold by the James G. Biddle in Philadelphia, to J. A. Summers. This would be a great addition to any collector for this very early Carl Zeiss scope.
