Handi Lockup Bar Question

I just got a lockup bar. It is the early style, but I’m missing two pieces the internal pin that goes from the cam to the spring and the pin that aligns the sliding part of the bar. That part is broken. I’m looking for some dimensions and/or some picture of each of those parts.

    Thanks to all who commented. Now all I need to do is get the broken part of the screw out.

    I checked the Handy Lockup Bar on my 325. Here, the screw in question is 1″, 10-32, fillister head.
    It just seems to keep the extension block from twisting or sliding off.

    We have in stock NRS-23, NR-253, and NR-255. I’ll have to check the assembly print to see what the screw referenced is and what it does–most likely a limiting screw as on the handi lockup bar.

    There is a screw that passes through the extension block into the bar, but this only keeps the block attached. NRS-23 is the only spring (also used in the Positive Lockup Bar), but it doesn’t expand or compress. The tension is released, via the handle, when the cam is backed-off the cam rider. lubricate the parts with graphite.

    I don’t have a Handy bar to consult, but will see one in May at the Center for Book Arts in New York.

    Thanks Paul. My Lockup Bar has a hole in the slide piece that gets pushed out to the bed rail. It looks like there was a screw and I’m guessing a small spring to push that slide bar back away from the press bed rail to release the lockup. In the main part of the bar there is what looks like a broken screw, but I’m not sure. That is the area that I still need to repair. Unfortunately your excellent drawing does not show anything regarding that screw…….Do you know if this was indeed the case?

    Here’s a drawing, but unfortunately it doesn’t show measurements.
