It is certainly one of the hundreds of different Pong clones out there. There are so many of them out there that many of them aren't even on klov at all. Many were made in very small numbers by tiny companies trying to grab a piece of the arcade game action.
It appears that Rover Leisure Products operated out of Arkansas in the 1970s, and appears to have not really been an arcade game company, more of a boat and RV dealer. Some old newspaper searches show some of their classified ads. The almost complete lack of reference to them on the internet tells me that you probably won't find much information on that particular game. It is probably fairly late to the action as far as Pong clones go (because of the color overlay). If I had to guess I would date it to 1976, based on the fact that they ran an ad for an electronics type person to help with their video game making in 1976 only to never mention them again in their later ads.
Tiny chance it is a Space Invaders clone instead but not very likely (particularly since you said the young lady described it as "Pong" on another message board). Is there a board in the thing?
