This is a National NV-180 portable VHS VCR. This unit was probably made for the National WVP-100N camera. This unit was working great for quite a while and was my main unit to use when I use to go around Wollongong and Jervis Bay filming stuff with my saticon tube colour cameras. I modified the unit a little bit by strapping to the side a big lead acid battery and connecting leads from it to the battery terminals. The unit lasted about 2 years and then started malfunctioning in some way so I stopped using it. I still have this VCR and I will have to look at it sometime and see if I can get it going again.
