Section of pigskin, now turned brown, with labelled squares drawn onto it, each fired at from a different range and with different powder by Churchill.
Gunsmith Robert Churchill fired guns found in a Battersea garage at this section of pigskin (the closest animal skin in thickness to human skin) to find out which had been used to murder PC George Gutteridge in Essex in the early hours of 27 Sep 1927. #NationalPigDay #Forensics125 #CM150 #ballistics
