Nice W & B . yes , pre 1891 , why , the word Germany is not on the tang . bone ? , take a close look at the pins , from the pics they dont appear
to be the same , could have been rescaled , pre 1891 W & Bs used mostly Buffalo horn , i collect straights , some 100 plus or so . several W & Bs
in the collection , all have buffalo scales . research , research , research pays off . especially in the collecting area .
hope this helps
