Welcome to the forum SirCee. Where are you in this old world? Not to worry about not having an R65. I've had a couple over the years. Gave the last one to my son but still have an R90. Lots of similarities. And like the others say, it's isn't a requirement. I love this forum because you won't find a nicer bunch of women and men who love the airheads. Very civilized and no rancor like so many forums. Fee free to ask questions and participate.
