I can tell you that the NV in the serial number stands for the year 1995.As far as the model this does not do a thing for identification.You will need to describe the firearm in question.This will include whether it is a shotgun,rifle,handgun.what is marked for the caliber,or gauge(if a shotgun).Single barrel or over under barrel.etc.then we will be able to help you further.
You must provide the model and caliber/gauge.
