Antoio Zoli 20ga.,3" magnum,o/u, double trigger.

I have an Anonio Zoli 20ga. with 3" magnum capacity. It is an o/u with vented rib, auto eject and double triggers.From what I have found, I believe this is a Senator model from 1986-1987. The stock is checkered and has scratches, as this was a well used rabbit and pheasant gun. The metal is in fantastic condition and has a substantial amount of engraving.

This was my father's gun, so I am not sure of the mfr. date. I have been told the gun values from $1500-1800. Can anyone confirm this. Thank you for your time, Bobby.

I am still trying to find a value for this Zoli o/u 20 ga. Can anybody help? Thank you for your time, Bobby.
