Long story short, got a B40 which was a huge mistake, wrong calculation on sizeso i got it return to the place i bought my B40 to xchange it for a K instead. THis shop is in Yokohama. So you see, they are not big timer like Brandoff, so they dont really take note about what leather or color code stuffs like that, so I got no info at all. But I m believe it is evergrain..TQ A, and the color maybe blue de prusse.
Oh B 40 is definitely tooooo big! I find 35cm big & heavy!
