you have the special 15mm bottom plate also, I have called around but no one even knows about these unless you get one with a used package. 19mm is probably the f35 standard, but having the option is great. I'd trade you my plate plus cash, but having it as part of your package is more worthwhile. You should get a good price with that viewfinder. How does the cinedeck attach? I know there have been a few photos before of these recorders. What's with the 15mm wooden camera rod mount on the side of the bottom plate?
