Of those that have taken their Kodak Panoram No.1s apart and renovated/fixed them...Can any of you help me??

I have a Panoram No.1 that swings the lens ok, but the shutter release(49) is not engaging and holding the swinging arm(45), so basically as soon as the tension in the swing mechanism is enough to get past the light baffle between the rear of the lens and the film box, it swings. The patent doesn't give any clues how the shutter arm 48 (the end of which slots into a hole 47 in the swinging arm 45 and stops it from swinging until shutter button 49 is depressed, pushing shutter arm 48 down, out of hole 47 and letting lens 45 arm swing ) is tensioned into the swinging arm hole 47. Is it just the flexibility of the metal shutter arm itself? I can move the shutter arm up and down but it never seems to home/locate into the hole in the swing arm of the lens (without taking the camera apart I can't actually see 45 where 47 is located - its all very dark in there!) The only thing I have noticed is that the shutter button 49 isn't held in the shutter arm and therefore the shutter arm has moved a few millimeters towards the the lens pivot. Could this stop it engaging in the hole in the swing arm. If i loosen the screw holding the shutter arm could I slide it back afew milimeters to this fix the problem (or is the screw held in ahole with no give/leeway)

I can move the shutter arm 48 up and down (up is a little worrying as I would have thought it could only go up when the swing arm hole was in the correct place. Could it be the swing arm is too high for the shutter arm to engage, if so is it easy to adjust the height of the swing arm, and if so, how? The nut at the bottom of the lens pivot 26 is right at the bottom of the thread, whereas on my No.4 which works perfectly it is slightly up the thread, so if this nut lowers the swing arm that might then allow the shutter arm to engage in the hole 47? Otherwise could it be possible that the shutter arm 48 has got out of line with the line of the holes 47 (shown as line between 10 and 10 on Fig 4). I can't see how this could happen given the arm 48 is held by two screws)

So far I haven't had to take apart the camera, and am hoping i can make these adjustments that will correct the problem without major camera surgery, just keyhole fidling and adjustment. If I can't is it easy to take apart a few panels of the camera to access the top of the swing mechanism (as shown in figs 3 and 4)

Any help would be very gratefully recieved!.

Ive included numbers from the 693583 patent to try and help explain what I'm asking.
