As far as i know they were modified random medical bits and bobs, I know the scissor like items are from a Maternity kit ( i have several of those scissors here at home, due to my wife working in the medical field )
heres a pic from the fim you probably already have ,but im not sure they all have names.
Missed this. Yeah that's a veterinary syringe. There's also a mastoid retractor in there, and the umbilical cord scissors. The rest are hard to identify.
I've got these tools molded already for the medkit that I am happy to announce is now underway again. I need to finish this functional piece first so that I can put it inside the backpack before I close it up so that I know it fits OK.
