Thanks Jack, I think you are probably right. It is a very good match.
Mowerfreak, the early plastic Rover catchers were not the best either. They were made of blue plastic and not UV stabilized. Anybody who left their catcher out in the weather soon found them fading and cracking. Hard to find any these days that do not have big cracks and holes in them. Rover released a black catcher later on which was far more durable. Both the blue and black catchers had the Rover logo in big letters on either side.
