What do you know about Altenloh Bruxelles ?? Total nothing ....... The name is completely wrong on the Polish site and that is taken over by others.
Altenloh Edouard, Altenloh Ernest and Altenloh Henri Edouard. These 3 companies located in Brussels with totally different Makers Marks and completely outside the period
