Does anyone know where I can find these 2 things? DAG is selling a brand new timer screw for 41US, which is expensive to me. Still can't fine the top part for my summicron, do I really just have to buy a cheap lens then take it off?

Also, I decided to buy a cheap i-22 and use the knob it has. Will it work? I heard that it will

I assume people would be more helpful if you were more precise...
"DAG", two bad photographs and "Summicron" at least to me rather seem a brain twister, than a serious request.
