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. > More

Serial number restoration by the etching method is commonly used to recover serial numbers or other identifying markings that have been obliterated from firearms, engines, electronics, and other objects. Serial number restoration gels provide improved adhesion for etching on vertical or inclined surfaces. > More

Ferrotrace is a non-toxic iron detection spray that reveals invisible iron traces left on a suspect’s hands after touching a weapon. Ferrotrace offers superior sensitivity, convenience and ease of use over other currently available field tests. Even after a weapon has been removed from a crime scene, an officer can quicly screen a large number of people by spraying Ferrotrace directly onto hands or environmental surfaces such as paper. If a suspect was in contact a weapon containing uncoated iron elements, the invisible iron traces will turn a dark violet color. > More
