I love cameras that have dealer labels that can give us an idea of the item’s history. I found this one in an antique shop in Massachusetts. I imagine this likely had an interesting life.

Breslau was a city in Germany. After WWII the surviving German population was expelled. The place is now a Polish city, Wrocław.

The Zeiss-Ikon Box Tengor cameras of this era came with Frontar lenses.
