Here's an authentic gonorrhea syringe made of glass from the 1870s period. This syringe was used to inject liquid cures for gonorrhea or venereal diseases directly into the sex organs (in this case, it was a male syringe with pointed end for sticking directly into the sexual organ)
These gonorrhea syringes were widely used, The main
treatment for VD was liquid mercury, which gave rise to the popular
saying in the 1860s..."An evening with Venus...a month with Mercury".
