As I said many weeks ago, Professor Opmmur sent me many documents so that I can scan them and share them with you guys. Here is the first one of them. It's basically a document about caduceus coils and numerous of their uses. Click here to see the file: Caduceus Winding It's a 9.3 Mb PDF file. I'll let the professor himself talk about the key informations that this file contains, as I'm not very knowledgeable when it comes to what this document is about. Enjoy!
