History on a new acquisition

Good day gentleman. I recently got hold of a few straight razors as a job lot. Including a Rudolf Schmidt 301.
I have tried and failed to find information on a 301.
I have however come across other numbers, such as 205 and so on.
Any further info would be much appreciated.
Cheers.Attachment 226710Attachment 226710

Post some pics of them, we'd all love to see them and it will also help in providing you information.
