I just had another look at the negs you posted.
Is it possible that the film was not correctly loaded in the tank - that the film slipped out of the grooves in the reel at one point and that adjacent coils were "folded" in the edge area and in contact with one another, thereby preventing proper development taking place? That would satisfy the fact that one film in the tank was OK but the other not, and that the problem is intermittent.
I know I've had the occasional spot of bother loading 120 film into spiral tanks and although I haven't experienced the outcome you did, I did have to unload and reload the film to clear the misalignment in the reel.
 
Hi Leigh
I think something like this must have happened but there is no way to check with plastic spool unless you disengage it and re roll film again even then you would not know if you were able to spool it correctly. I always clip the corners of the film because I found it was jamming in the spool before. It spools nice and easy now. Maybe I should wear a cotton glove on my left hand when spooling ? I touch the side of the film to feel end of the roll? Grasping for straws Ah. Maybe grease on my fingers was left on the edge of the film? Again I do wash my hands before I start developing film. I don't know. So many variables.

As I said before I did swap lenses from one camera to the other just to prove that it was not a camera problem like bellows. I did not change lens but lens and shutter together. Australian body with Color Skopar blotches appear Jurgens body with Vaskar lens no blotches. I do not know how many variables I have introduced to the equation. I'll keep you posted as I shoot more film.

You're pretty sure it is a lens problem though? If so, I'm betting that at least one lens element is cross-threaded in the shutter or that he didn't get the lens square to the front standard (maybe something stuck between shutter and standard). I suppose that it is also possible that the elements he used came from two different Scopar lenses (something you are not supposed to do).

Thanks Fallis
I looked at the lens set up, and it looks parallel to the lens board I compared it to Vaskar lens and board same distance from the shutter to the lens. Lenses do not look like as cross threaded. And looking through the lens with the back light it is clean and clear. I will find out what is causing this it is probably obvious I have not being able to see it yet.

Today I decided to do what you guy's were suggesting. I took a roll of color film I had few and went down town exposed this roll and let the local shop develop it . I also brought my negatives with little bubbles to show to the technician.
Well: It is not camera or lens. The negatives came out normal. Now it is left for me to find out if the dirty reel or contamination with photo-flo caused the blotches.
Thanks to every one that chimed in and made me look in the right direction and in the process maybe helped someone else.

Cheers Greg
