Well, Let's see if I can mess this up a little bit more. I got the pic posted, but it's a different pic and the plates are in different order, so my previous post will not make sense. I guess I better start over. These 3 WRA butt plates are all marked 2S, but they all have subtle differences. Look at the area where the trap door hinge pin goes through. The one on the left has a slight raised lump right over the pin location, much like SA but not near as prominant. The one in the middle is perfectly flat, and the one on the right is also flat, but looks like it has been ground slightly to make it even flatter. I have some more WRA plates all with these same differences so I think these are just 3 common variations of WRA butt plates. Check out the lower checkered area and see that it comes to sharp points where it wraps around the trap door. WRA butt plates are the only ones that come to sharp points. I think that when new, WRA had a slightly more prominant border around the checkering pattern than other butt plates, but they all started out with a border, so once they got a little worn it was no longer a good indicator. I have a couple of WRA butt plates with no border at all. It is worn clear off. You will also see that the checkering pattern on the trap door is slightly different on each plate. These types of slight differences, even among brands is what causes some people to have trouble identifying butt plates. The plates you are asking about do not have these WRA indicators. I still think both plates you are trying to identify are WWII SA plates. [IMG=left]http://img.photobucket.com/albums/v467/2cufms2/WRA%20HRA%20butt%20plates/MVC-004S.jpg[/IMG]
