Hello! I ordered a Montegrappa Ducale Murano Mare and received it today! It looks great and I'm looking forward to inking it!

I noticed that the converter has a small coil spring inside. It is not attached to anything and just floats around inside the reservoir area, between the plunger and the opening. The coils on the spring are touching each other such that it would have no compressive springiness to it.

What does this do? Does it complicate anything when cleaning?

Thank you!
