This is an undated Luger that I picked up recently, which I think is a Simson. I'm a bit puzzled because it is marked S on the toggle and that usually means Mauser doesn't it? The proofs seem to me to be Simson though and include the droop eagle 6 mark. The S/N is 1868 and all the numbers match. Overall it's not in great condition as there is some corrosion. Am I right in believing it to be a Simson and would anyone know when it was made?
Here are some pictures:
