Funny thing happened today,
I got that heiland flash with an actual graflex clamp on it for 23€ shipped, I thought it was a pretty good deal. It showed up today, it has a very old threaded square clamp lever holder on one side! I think this will be perfect for my jawa blaster. It didn't have a V2 lever though! that would have been crazy right...
And here are some clearer screenshots. It's hard to see from stills, but when in motion it really does look like braided cable. You can see the texture.
By the way, since this is brought up again, I discussed this quickly in another thread but, it turns out that those threaded square blocks are always inside the bigger square side of the clamp on a graflex. the exterior box is just glued or forced onto that smaller square box and it can fall sometimes. This is most probbaly what happened on the V2. it's not a replacement part.
No idea for the longer lever though!
