The Pelikan 520 was introduced in 1956 and was a  specifically Italian product. The reference basis for the model was the Pelikan 400 thus Pelikan 520s can be found as 520N and 520NNs, too.

These pens are extremely rare nowadays and it is not easy to find them in pristine condition. 

This Pelikan 520 is in excellent condition and it is fitted with a very pleasant EF 14 ct gold nib which writes like a dream.

The overlay is absolutely perfect with no dings nor scratches,
