What is strange though is the numbers don't align they are staggered as if stamped individually and not a machine press with all numbers aligned together.
That's not strange that they don't aline on the body stamps. Mine do the same thing the B and the 8 are set lower. The radiator support one is a little blurry but you can still see the first 2 number are lower. View attachment IMG_4443 (640x480).jpg
