I'm new to The Firing Line, and I am looking for help with a Stevens Mod. 520 12 ga. pump. I have an early model that has an inertia block to release the slide lock when the gun is fired. I have been unable to find any drawings that illustrate this part. I have found an old thread here at TFL from 9/9/2007 that included some great photos of this inertia block. The poster was "jus1derin".

The problem I am having is installing the slide lock spring. This spring is not visible in jus1derin's photos, and I can not figure out how to install it so that the slide lock engages. Can anybody help with either photos or a description of how this spring is installed?
