Agree with the previous posts. I have a Retina IIa and IIIc (small c), both are fantastic cameras. The IIIc was missing the flip up lid for the meter, so I had to buy a parts camera to get the lid. Little did I know that depending on when the camera was made that the lids are designed differently. My IIIc had a lid catch on the bottom right of the meter bezel, the parts camera lid had the catch on the left side. Luckily the meter was working in the junker, so I was able to swap the entire meter assembly which included the lid.
