Rare H. Pfau Germany Surgical Tools - Lot of 12 numbered Vintage

I have held on to these for many years. I am guessing that they were related to the field of Ear Nost and Throat Surgery as my Grand father was an ENT Surgeon from Germany. His practice was from 1932 to 1957, however I am not able to age the tools nor confirm exactly what their design was for. Maybe there is a collector of Vintage surgical tools that has interest...
