Could you post a picture of your razor?
To my best knowledge the company C. Jul. Herbertz from Solingen does not produce any razors it´s just a retailer.
They sell everything from Thiers-Issard and Puma to stuff they buy godknowswhere and sell under their own label.
A picture would help to get a clue what you bought.
