I picked up this silver sewing awl today (or at least that's what I think it is). It's marked with the sword for Dutch silver, it looks like the 1906-1953 sword to me. The maker's mark is *B* (3rd photo). I looked in various online databases but I did not find a match (closest thing was *B* in a shield with the stars slightly above the B). Does anyone recognize this maker's mark? I would be very grateful for any information.
