This Serial Number Restoration Kit is designed to provide the proper materials to assist investigators in recovering obliterated serial numbers or other markings on firearms and other metallic weapons. When a serial number is stamped into a metal surface, the underlying metal grains are compressed and deformed deeper than the impressed number or mark. This difference in the metal crystal grains causes them to react differently to chemical etching and can, in many cases, allow them to be recovered. The reagents in this kit are patterned after ATF recommendations as taught at the Serial Number Restoration Training Course that the National Firearms Examiner Academy. The kit also includes instructions, acid neutralizer, wet or dry polishing paper, fine file, gloves, safety glasses, cotton-tipped applicators, dropping pipettes, protective oil and clay dam material. Packaged in a sturdy plastic carrying case with fitted foam liner.
