The deal is for a great matte box from Chrosziel company . It does not its regular marking on the side but I am almost certain that is a MB-415It comes with two trays 410-31 and 402-04 . It also includes two step down rings that screw on into the matte box  410-39 and 45-0-20. I am adding a Matte  450-MA .The rails that fits the matte box is 15mm . All the good above for just $99 +$55 shipment . Because of its lower price the sell is final with no return policy .
