Very nice razor, E. H. Robinson was a Jeweler, Silversmith, Watch Maker and Optician. 1850-1910. Probably a Sheffield maker, made for E. H. Robinson in the later part of the 19th century.
Where on Earth do you find this info?! my google button must be broken hahaha! I have only had one razor marked Robinson, Bishopsgate within and tried finding info, never came up with the goods.
Another awesome example here, thank you!
