Having recently acquired not one but two of these VG6DR systems I can confirm they are narrow band. One of them is date stamped from 1992 and the other one is from '94. I have no idea how long they sat before I bought them but I plugged in batteries and they fired right up and work great. I have to say that they are very good systems. Honestly they are the only systems I've ever owned that have virtually no servo twitch upon powering up nor do they get interference twitch. I have newer fancier 72mhz systems like a 6channel JR and Futaba 9CAP Super and they all twitch. These Vanguards were high-end radios in their day. They are six channel and have dual rates. For a beginning aircraft modeler that is plenty of features in my opinion.

Other than the band your biggest issue is using it with a modern ESC. They have reverse mounted pos/neg posts in the servo plugs compared to the typical JR and Futaba stuff. You can make adaptors though. Here is one of mine.

Sad they stopped making them:
