The G. Tiemann Co. of New York City was and is a maker of surgical instruments. This particular set dates from the end of the civil war and would have been a military field doctor’s postmortem or autopsy kit. A good thing too, as in the days before sterilization and Lister, the safest surgery one could have would be an autopsy! This kit is in as good of condition as we’ve ever seen with allpieces intact, bright, shiny and functioning as they should. Near perfect.
