Wow! A Werra was my very first camera back in the mid '60's. I think it cost about $30 and it was the only camera my Mom could afford.
I bought a Werra for my father a few years ago and it started him collecting old cameras. The Werra was the first camera he bought when he left school and started work which would have been early sixties and was probably all he could afford too.
Quite an interesting design with the wind on mechanism around the base of the lens.
