The answer seems to be no. If you have been convicted for a DV assault 4th degree case in the past you lost your right to possess a firearm and you have to petition a court of record, a Superior court in order to get this right restored. Got to the court where the case is from and file a petition with Superior court to be reinstated. It isn't easy but possible if your record isn't bad. If you only have this one case you have a good shot. If you have several cases. Not so much.
There is no confidentiality online. If charged with a crime, the accused is presumed innocent until proven guilty beyond reasonable doubt.
Best person to ask is your attorney. If you cannot find your attorney, or find a local attorney on Avvo, a good place to look is the website for the National Association of Criminal Defense Lawyers (NACDL.org)

The statute of limitations applies only to the period of time between when you committed the crime, and when charges were filed. There is no statute of limitations after conviction.
You may have a better chance of restoring your firearm rights if you first vacate your assault 4 conviction. See here: http://www.courts.wa.gov/forms/?fa=forms.contribute&formID=38
