Focusing Screen Type A 6x8 Matte for Mamiya RB67 Pro SD Allows for precise focus adjustment. This is a long-term storage item and is old. It is completely unknown whether it has been used or not. There appears to be a slight stain to the untrained eye, but I was unable to capture it well in the images. It is only noticeable when held up to the light, but please refrain from purchasing if you are seeking perfection or are overly concerned about details. The original box, storage case, and instruction manual are included. The original box and storage case are quite damaged. For shipping, we will use simple packaging and recycled materials. We are looking forward to your purchase if you understand that this is a long-term storage item that has been inspected by an amateur. - Brand: Mamiya RB - Product Name: Focusing Screen No.3 Rangefinder Spot - Features: With center focus function - Accessories: Original box, storage case Thank you for viewing.
