I have one of those also with different slides, the Color bar Slide is Really only for Sony cameras, the lamp in the pattern Box is Regulated for Light output and there is a light Filter in the pattern Box, it is on a slide in tray, that is needed for proper Color Temp Adjustment, I think the model of this Box made for Sony is a ptb-500 or ptb-800, there are 2 Models ,one of the Slides is corrected for Sony Single Tube Trinicon Color Camera alignment, the other model for pro 3 Tube cameras.
