Abstract
Firearm serial numbers are a critical identifying mark, and restoration of destroyed serial numbers is often crucial for prosecution of a criminal case. Currently available methods, including acid etching and relief polishing, present serious limitations A method is presented utilizing electron backscatter diffraction (EBSD) in the scanning electron microscope (SEM) which allows for clear visualization of die-stamped imprints which have been completely polished away. Evidence of the stamp can be observed to a depth of approximately 760 µm below the surface. With further development, the described method is capable of fully restoring an 8 character serial number in approximately one hour.Citation
