This is my very first straight razor, bought at a flea market in summer 2015. Founded in 1827 by Friedrich Wilhelm Backhaus in Hilden near Oligs. Registration of the trademarks "Clein, Jahr and Stern" in December 1854. Here a knife from the brand Stern Nr.12 in 4/8. Since 1901 a spelling reform...
Here an old, rare knife from Belgian manufacture (province / city of Namur) in 6/8 with lead wedge and horn handle (presumably). A really heavy knife. Regards Brille
Here is a knife not from Solingen but from Bad Bergzabern (Rheinland Pfalz), from the Ziegler cutlery and grinding shop. The company was founded in 1827. The razor is 5/8 - 6/8. Regards Brille
The knife factory Eduard Carl Müller (Solingen Weyersberger Straße), founded 1894-1899. In 1904 the trademark "Man with a rolling barrel" was registered. Here a razor in 7/8. Regards Brille
Founded around 1859. The brands Aurora from 1906 and Guillermo Hoppe from 1922. (Source: German knife and sword maker) Here is a Guillermo Hoppe number 14 in a full 7/8. Regards Brille
