This bino shows the excellent qualities for which miss Bleeker is known. The first thing literally meets the eye, is the quality of the optics – and the precision the instrument has been built. Razor-sharp images of great contrast and excellent rendering of colours with an enormous definition.
Greatest quality: the rest in the images only obtained by Leitz at the time.
On the left side there is an engraving of the Royal Dutch Navy ( a "K" and a "M" divided by an crowned anchor) and the number cl.nr 575.20.08.03. On the right side you find "Dr. C.E.Bleeker Zeist Medibu 6 x 30".
On the left bridge to the front, there is the serial # 18922.
