"The Cooke Series V, F/8 lens began its run about 1899 and was designed in continued collaboration with Dennis Taylor as an even more refined variant of the Cooke Triplet lens. It was offered as a Cooke process lens a little over ten years later because of its special clarity of definition. The lens was especially suited for commercial photography requiring a microscopically fine definition in average lighting conditions. (In 1912, a Professor Pickering of the Harvard Observatory chose several of the Series V focal lengths to record nightly sky survey shots of the stars from Cambridge, Massachusetts.) Until about 1925, the Series V, F/8 lenses were made in these focal lengths: 9 inch for 5x8 format, 11 inch for 8.5x6.5, 12 inch for 8x10, 16 inch for 10x12, 18 inch for 12x15 and 25 inch for 16x18. -Barbara Lowry

Designed by Harold Dennis Taylor. The Cooke triplet proved to be an influential design, it was made in several series by Taylor, Taylor & Hobson and was widely copied by other manufacturers. The original patent shows a lens consisting of two plano-convex elements each side of and equidistant from a bi-concave element. The series V was intended for architectural, copying and reproduction work. -Early Photography

The date of this lens appears to be 1899 and 1925 and it is a process lens, meaning it should produce very sharp images and could even be used on an enlarger or process camera for copy work too.  I am currently making a lens board for this lens and I will get it mounted and take some photos and post them here.
