Hi folks,
I have a question about the material of the scales on my first junk shop restore:
The material is brownish black and the surface is dry. When sanded lightly with 1000 grit, the result is a rust colored dust.
What is it? hard rubber, composite??
Blade :J.A HENCKLES/ SOLINGEN -12. Not marked Germany. 6/8ths
Any one know the age??
