A Lentz's Compact Operating Case, No. 10, Style A, as seen on page 45 of the "Charles Lentz and Sons' Illustrated Catalogue and Price List". The kit includes, among other things, several surgical instruments, including scalpels, a saw, a tourniquet, as well as a trepanning set.
This is an instrument for removing a fetus. This perforator is very similar to Smellie perforator but it has thinner and longer shanks. It has a pin lock and works much like a pair of scissors. The existing label reads: 'C. Lentz'.
