It never occured to me to take a picture because the guy had worked for us for over 3 years, including fabricating parts for 3 other cars of mine. I'm reluctant to diasassemble the driver's door interior because the 1st door was such a pain. All I can say is that it is the collection of parts as a unit between the exterior door handle's interior unit and the spring-loaded unit that disengages from the door post attached to the door frame.

BTW....thanks for replying. You can see my Abarth (440582) in the image archive. It's had significant upgrades throughout and even recently (but still matching numbers 750 cc engine) and was successfully raced on the East Coast (and Sebring) in historics back in the 1980 timeframe. Just drove it a few days ago for the 1st time in 9 months and it started right up and ran without a problem. (LOUD litte beastie.)

I guess you didn’t understand the cars are hand made. Many different techniques were used on the door mechanicals. Maybe someone on the site will be able to assist.
