Help to identify old ANASTIGMAT lens 1890 era

[aspegicus]

Hello! I got my hands on an old camera from the 1890s era I was told. However I cannot find anything on its ANASTIGMAT f/6.3 lens (see pictures below).
Could someone help me identify the characteristics of this lens and maybe its coverage?

Much appreciated

You can read on the barrel Aldis Anastigmat 8 in f/6,3
Affordable anastigmat when it was produced
A lot of coverage for 5x7.

Thanks a lot! I couldn't read "Aldis" clearly or understand the 8 IN signification.
