The bend and milling in the bolt handle does not look right, or like those I've seen. And, although the original bases came from Redfield, I believe they were unmarked? The receiver may be the real deal. I've seen several posts here and elswhere of people finding nice sporters with A4 receivers.
I also just pulled a Remington M1903 and a 1903a3 from my safe with a "2" in their serial. The bottom of the 2's are each straight, and not wavy like the serial of this rifle.
