The base is marked with the French Swan Control Mark (small mark on the left) and two other marks I can't identify. I guess its a German model, early to mid 20th century with spurious old looking marks...

Just under the head, the body is marked with the French Swan Control Mark, struck twice.

I have two questions -
1. Does anyone recognise the main marks?
2. Why is the French Control Mark struck twice? I have seen this before but looking online I just can't find any reason why.
Thanks in advance,
Jonathan
