I got my 2 CD:s with 1946 Car builders cyclopedia yesterday and found a picture of the lock. The shape made it clear how it could be push up to release the coupler.
Thanks for your input.

Hi all,
I do understand how an uncoupling lever works when it lifts the pin from above to release the coupler.

I don't understand how it works when the lever is under the coupler. It then has to push the pin up but wouldn't the part that is pushing the pin up lock the coupler?
Simple answer, the lock ("pin") is more complex than a simple metal pin, it's actually a sliding metal block with a notch in it. So, It's accessible from either top or bottom. Bottom opperated couplers were fond to be more reliable, seemed to become standard by WWII.
