Sent you a Pm. Got a spare caddy. Got other random parts as well. Think i have a spare camera for a U1 as well. Had thought about trying the H2 updated camera software on the U1 Mk2 of mine like Toughbook did on a H1 or a 19 a few years ago for better camera control on the U1. I know you are trying to get it to a external camera. You can also use the factory camera flash as a flashlight.
