RV53? I don't know that model #...........
I think that you might mean JV53............
It a 13" Custom Pro Kip with an open back & a double tombo web (basically a reinforced single post). The leather is a 6oz premium kip. It's one of the gloves I regret not getting ahold of. Personally, I'd take a Custom Pro or Custom Pro Kip over anything else by anybody else!
