Detlef,
Thank you for the warning. I started with the fingernail polish remover this afternoon. I bought the remover and cotton buds by myself and it is mine. When i'm finished i will give it to my daughter.
It looks i have removed most of the paint. The wood of the hilt and the upper part of the scabbard are of a lacquered dark wood with spurs of wearing. If i have time to spare i will do the blade in the weekend. It is pitted and a bit rusty. it looks i will end up with a nice sewar.
