the first thing to look at, if possible, is a side profile looking for a round ear design, also look at the staking around the pin to see if it matches yours.

SRiverrat11,

Look over this link and pay attention to the rear of the side blade protectors.
Study and note the longer arcing curve found on the WRA used frt sights.
See how it doesn't have a SKI SLOPE type back edge.
Also note the style of punched stake mark used to pinch in the frt sight's pin.
Most often the frt sight pins staking on WRA's looks like a O over/around the pin, pinching the metal on the sight to tighten (stake) the pin.
In time you'll know a WRA at a glance.
Hope I've made some sense, sometimes tough finding the right description....................

POST #8 in this link will show a before cleaned WRA's frt sight still having some of the metal hanging from being staked:
