Bell & Howell Camera Differences

Check out my block https://www.propchopshop.com/ These are used for the Resistance Crait Macrobinoculars / Neuro-Saav ND.621 Rangefinder in The Last Jedi. The scene is near the end of the movie where Poe Dameron is viewing the approaching enemy. Both of the cameras I have are Director series, but have some significant differences and I don't know which one is correct. The correct one could also be the Sportster version as well, which I don't have.
