"MODEL VP4444 VINTAGE PAGE ALERT VEHICLE SECURITY ALARM SYSTEM by SUNSENTRY (SUN ELECTRIC CORP.)"- Never used rare model VP4444. A great security addition for your Classic Car or Truck, as made for none computerized vehicles. You would have to get installation instructions somewhere (should be the same as the older model 4000 series Page Alerts). Most pieces still in the original cellophane/plastic, however, I won't guarantee that the AA battery still holds a charge. This was something that I found in my deceased uncle's inheritance. You get the exact items in my photos. Thank you for looking.
