Home Forums Hunting & Shooting Winchester Collectors Featherweight bolt knob

Ok, serial # placement on bolt; hoping you guys can shed some light on this.....

1955 featherweight, serial # placed below flat on anti-bind bump, so clearly visible with bolt closed. Additionally, dots seemed spaced further apart than typical, enough to appear quite digitized; and last digit 5 had extra dot closing it's tail to where it resembled 6; receiver was stamped 5. Poor attempt at refurbished bolt, or apprentice engraver at the factory ?. I passed on the rifle, but often wondered.

Thanks in advance for your input.
