Below is a picture of the rear sight on the Perris Special and the rear sight on a SRC I have that is within 300 numbers of the Perris rifle. As you can see, the rear dovetail is moved much further forward on the Perris rifle, which I have to believe was done so they could accomodate the long rear sight. By the way, I put the micrometer on the end of both barrels and they mic identically, so for this rifle, they used the one standard short barrel they had on hand at the time. I understand (thanks Rick) that the known serial number range is 49,xxx through 52,xxx. This one is 49,00x, so it may well be the first one made and if not, one of the very first. I am very curious if any of the ones made after this had a lighter barrel. Ah, the mystery of it.
