Door Handle / Latch help

[JT Burkard]

This 1976 450sl I have is slowing becoming a better car over the last month or so. Thanks to everyone who helped in the past.

The drivers door would not open from the outside. I had to get in from the passenger side and open the door from the inside. Yesterday I decided to have my mechanic at my shop (I work for a classic car dealership) to take a look at it since I didn't have the time.

He is flipping because 1. Its German 2. He hates door work 3. He can't figure it out.

So far we found a chrome piece on the bottom of the inside door that looked like it went onto the outside handle that actuated the door latch mechanism. It was missing the small set screw. From there he says its very loose when connecting to the latch and might be missing something else.

I can't find any info on the internet and tried to do a search here but couldn't find anything. Does anyone have access to an exploded diagram of the door latch and handle mechanism so we can see what parts are supposed to go where and if we are missing anything?

Thanks!
