Bessa R Double Exposure fault

[lZr]

I followed a thread about doble exposure with Bessa R pushing the rewind button to cheat the cock machanism. Nada! Yes, I followed my frame counter up to 40 (perhaps), but the results show overlapping frames. I wanted to expose the camera with 2 lenses - one on the table and same lens mounted. Epson 4990 scaner. Look and comment, please.
I am ready to do it again

I'm not sure what you wanted to try. Please, could you elaborate a bit more? 2 lenses? 2 different focal lengths? 2 different positions? Did you move the camera in between shot?

I wanted to show my camera with 2 lenses (I have only 1 Lensbaby lens). So, shot #1 was taken with the lens on the table (cap stays on table twice). Second shot with the lens mounted on the camera. If all goes nice, you will see the lens on the table and on the camera. In reality, after pushing the rewind button and cocking the shutter the film slides to the next frame, even worse - the next shot overlapped. And Yes, there is a slightly move, because the setup was simple done, knowing the camera will not be back same place.
You see 2 different experiments

i think this isnt really a "kosher" way to do this. Bessa wasnt designed for double exposures. But you might want to try to hold the rewind lever steady while cocking the shutter so that film doesnt move. Still I guess it could move a little bit.

Right, not kosher! But holding the button (bottom plate) was pushed steady. Next experiment will take the rewind lever into account. I checked the sprocket wheel disengaged nicely while the camera was open

I've done this in the past with other cameras and it will only really work if you can be sure the film is tight across the back when you do it. Otherwise once you press the rewind button and disengage the film rollers, any slack in the film will allow any forward tension to pull the film.

I've just examined my L (my R has film in it), and with the rewind button depressed the film sprocket still winds freely when the shutter is cocked if it is not held back - not with much force, but I'd guess enough to move a loose film a little way.

So I'd try the suggestion of winding back the rewind lever a bit and holding it tight to see if that helps.

Thanks Alan. I'll do it next film again and pay more attention to rewind lever position.
After closer examination of the second image, you see 2 lenses as I palnned, but the next frame is overlapped
