Very old, no doubt. What are you going to do to suspend the rust; have you already thought about it ?

It doesn't seem very active at the moment so don't think I'll put a lot of time and effort into preserving it. If you want to do that well, you have to put it in demineralized water for a longer period of time (the thicker the object, the more time it needs), change it regularly and measure the water it has been in for amount of released minerals. Repeat this as long as necessary, so until you no longer measure anything. Treat only after this. At least, this is how professional restorers would do it.
