Oracle Cartridge Cases of .32 ACP Dataset

As part of the Oracle project, we were granted access to the .32 ACP cartridge case dataset from the SNPS police forensics laboratory in France. After curating the data, we obtained 4,612 images representing 170 different models of .32 ACP firearms. We would like to thank ballistics experts Noëmie Barrié and Gregory Jalabert for their help in curating and obtaining the data. A supplementary PDF (in french) containing our research notes on the 170 models and their bibliographic references is also provided.
