Mixed up a real and repro leaf
I managed to find a old post of mine from 2010. I had a Flip Sight that had a nearly rusted in half spring. It caused the leaf to just flop back and forth, having lost spring tension.
I bought a Repro sight from Nick Daley (sp?) to rob the spring from. IIRC at that time you couldn't find these springs listed for sale anywhere. Anyways I took the New Repro and the real one apart to swap the spring. Project got put on hold and when I got back to it I couldn't remember which Leaf was the real one.
I posted pictures here and fellow member ScottR pointed out which Leaf was the Real one, by comparing the bottom pivoting area that contacts the leaf spring.
Below are the 2 Flip Leafs I had mixed up, #1 is Left, #2 is Right:

Second Picture #1 Was Decided as the Original GI Leaf.

Also:
Wasn't there just 1 style bottom pivoting area on all GI Flip Sights ?
I recall seeing one of the Spec manuals FM23 -7 May 1942 that shows the side profile/alignment when the short leaf is in the upward position.
This seems to show that going up from the center of the pin hole would line straight up Flush with the outer edge of the small peep thru hole of the blade.
But there must have been a change or the Sight wasn't built this way because my above example would not line up the center pin hole straight up to the front edge of the small leaf.
Other changes can be found in FM23-7 like dropping the Hammer Stop on page 8
